Ice Station Zebra is a 1968 American spy thriller film directed by John Sturges and starring Rock Hudson, Patrick McGoohan, Ernest Borgnine, and Jim Brown. The screenplay is by Douglas Heyes, Harry Julian Fink, and W. R. Burnett, loosely based on Alistair MacLean's 1963 novel. Both were inspired by real-life events that took place in 1959 (the flight, loss and search for Discoverer 2). The film concerns a United States nuclear submarine that is rushed to the North Pole to rescue the personnel of Ice Station Zebra.

The film was shot in Super Panavision 70 and presented in 70 mm Cinerama in premiere engagements. The original music score is by Michel Legrand.

Ice Station Zebra was released on October 23, 1968, to mixed reviews, and it was not a box office success, earning only $4.6 million over its $8–10 million budget. At the 41st Academy Awards, the film was nominated for Best Cinematography and Best Special Visual Effects.

Plot A satellite re-enters the atmosphere and ejects a capsule, which lands approximately northwest of Station Nord, Greenland, in the Arctic Ocean ice pack. A person approaches, guided by a homing beacon, while a second person secretly watches from nearby.

Commander James Ferraday, captain of the American nuclear attack submarine USS Tigerfish stationed at Holy Loch, Scotland, is ordered by Admiral Garvey to rescue the personnel of a British scientific weather station moving with the ice pack named Drift Ice Station Zebra. This rescue is actually a cover for the real mission.

British intelligence officer Jones and a United States Marine Corps platoon join the Tigerfish while in dock. After setting sail, a Kaman SH-2 Seasprite helicopter delivers Captain Anders, a strict officer who takes command of the Marines, and Boris Vaslov, a Russian defector and spy, who Jones trusts. The submarine sails beneath the thick Arctic pack ice, but is unable to break through with its conning tower. Ferraday orders a torpedo launch to break a hole in the surface. When the inner torpedo hatch is opened, seawater rushes in, flooding the compartment and causing the submarine to nose-dive. The Tigerfish is only saved before reaching crush depth by pumping air into the flooded area. After an investigation, Ferraday discovers that the torpedo tube was sabotaged. Ferraday suspects Vaslov, while Jones suspects Anders, continuing to refuse Ferraday's demand for more information about the mission's true objective.

The Tigerfish rises and breaks through thin ice to the surface. Ferraday, Vaslov, Jones, and the Marine platoon set out for the weather station in a blizzard. On arrival, they find the base almost burned to the ground and the scientists nearly dead from hypothermia. Jones and Vaslov question the survivors about what happened.

Jones reveals to Ferraday that he is looking for an experimental British camera that used an enhanced film developed by the Americans. The Soviets stole the technology and sent it into orbit to photograph locations of American missile silos. The satellite also recorded all the Soviet missile sites. After a malfunction, it crashed near Ice Station Zebra. When Soviet and British agents arrived to recover the film capsule, the scientists were caught in the crossfire; the only way of finding the capsule being a tracking device lost somewhere in the station. Ferraday sends his crew out to search for the capsule. Just as Jones finds the tracking device, he is knocked out by Vaslov, now revealed to be a Soviet double agent and the saboteur. Anders confronts Vaslov and the two men fight before the dazed Jones shoots and kills the American. Vaslov feigns his innocence to Ferraday, who discovers a detonation transmitter for the capsule, which he keeps concealed.

The Tigerfish detects approaching Soviet aircraft. Ferraday lets Vaslov use the tracker to locate the ice-buried capsule. Jumping from their transport planes, Soviet paratroopers land nearby and move in as the Americans work to free the capsule from the ice. Their commander, Colonel Ostrovsky, demands the film, threatening to detonate the capsule's explosive booby trap should the Americans attempt to escape with it. After Ferraday hands over the empty container, a brief firefight occurs when the deception is discovered. In the confusion, Vaslov tries to take the film, but is wounded by Jones. Ferraday orders him to give the film to the Soviets. The canister is sent aloft by weather balloon for recovery by aircraft. Moments before it is taken, Ferraday activates his own detonator, destroying the film and denying either side the locations of the other's missile silos. Ostrovsky concedes that both his and Ferraday's missions are effectively accomplished, and the standoff ends, each side beginning the return to their home countries.

The Tigerfish completes the rescue of the civilians, and sets sail back to Scotland. A teleprinter machine report frames the incident as a successful cooperative "humanitarian mission" between the West and the Soviet Union.

Cast

Production Development The film rights to the 1963 Alistair McLean novel were acquired the following year by producer Martin Ransohoff, who hoped to capitalize on the success of 1961's blockbuster adaptation of a 1957 McLean novel into The Guns of Navarone, Hollywood's #2 grossing picture that year. He expected the film to cost around $5 million. Ransohoff's company, Filmways, had a deal with MGM to provide financing.

Paddy Chayefsky, who had just written The Americanization of Emily for Ransohoff, was hired to write the script.

Navarone stars Gregory Peck and David Niven were initially attached to the film, with Peck as the submarine commander and Niven as the British spy, plus Edmond O'Brien and George Segal in the other key roles. John Sturges was borrowed from The Mirisch Company to direct. Filming was set to begin in April 1965, but scheduling conflicts and United States Department of Defense objections over Paddy Chayefsky's screenplay because they felt it showed "an unfair distortion of military life" that would "damage the reputation of the Navy and its personnel" delayed the start. A new script was commissioned.

In January 1967, MGM announced the film would be one of 13 movies it would make during the next year.

Casting Scheduling conflicts caused the original cast to be unavailable when filming began in the spring of 1967. Rock Hudson had replaced Gregory Peck by February. After making four flop comedies in a row, Hudson had been keen to change his image; he had just made Seconds and Tobruk, and Ice Station Zebra was an attempt to continue this. According to his publicist, Hudson personally lobbied for the starring role in this film which "revitalized" his career. In June 1967, Laurence Harvey and Patrick McGoohan joined the cast as the Russian agent and British agent, respectively. In July, Ernest Borgnine replaced Harvey. Other key roles were played by Jim Brown and Tony Bill, who signed a five-picture contract with Ransohoff.

There were no women in the cast. "It was the way Maclean wrote it," said Hudson.

Filming Filming began in June 1967 using Metrocolor film stock. The film was budgeted at $8 million. Principal photography lasted 19 weeks, ending in October 1967. By the time it was finished the cost had risen to $10 million.

Ice Station Zebra was photographed in Super Panavision 70 by Daniel L. Fapp. The fictional nuclear-powered submarine Tigerfish (SSN-509) was portrayed in the movie by the Diesel-electric Guppy IIA class submarine when seen on the surface. For submerging and surfacing scenes, the Diesel-electric Guppy IA (SS-322) was used, near Pearl Harbor. The underwater scenes used a model of a nuclear submarine. George Davis, head of the art department at MGM, spent two years researching interior designs for the submarine.

Second unit cameraman John M. Stephens developed an innovative underwater camera system that successfully filmed the first continuous dive of a submarine, which became the subject of a documentary featurette, The Man Who Makes a Difference.

During filming, Patrick McGoohan had to be rescued from a flooded chamber by a diver who freed his trapped foot, saving his life. As he was also making his television series The Prisoner during principal photography on Ice Station Zebra, McGoohan had the episode "Do Not Forsake Me Oh My Darling" re-written to have the mind of his character transferred into the body of another character.

Release Ice Station Zebra was released in some theaters in the Cinerama format. However, it was not popular with audiences, losing substantial money. It premiered at the Cinerama Dome in Los Angeles on October 23, 1968, where Rock Hudson was heckled at the premiere. The film opened to the general public the following day. The film earned theatrical rentals of $4.6 million domestically.

The escalating production costs of this film, along with the poorly received The Shoes of the Fisherman at the same time, led to the transfer of MGM president Robert O'Brien to chairman of the board, though he resigned that position in early 1969, after both films were released and failed to recoup their costs.

Reception

Critical response On Rotten Tomatoes, the film has a 44% rating based on 16 reviews with an average rating of 5.50/10. On Metacritic it has a weighted average score of 49% based on reviews from 9 critics, indicating "mixed or average" reviews.

On December 21, 1968, Renata Adler reviewed the film for The New York Times: "a fairly tight, exciting, Saturday night adventure story that suddenly goes all muddy in its crises ... It doesn't make much difference, though ... The special effects, of deep water, submarine and ice, are convincing enough — a special Super Panavision, Metrocolor, Cinerama claustrophobia ... (The cast) are all stock types, but the absolute end of the movie — when the press version of what happened at a Russian-American polar confrontation goes out to the world — has a solid, non-stock irony that makes this another good, man's action movie, (there are no women in it) to eat popcorn by."
