The Journey is a 1959 American drama film directed by Anatole Litvak. A group of Westerners tries to flee Hungary after the Soviet Union moves to crush the Hungarian Revolution of 1956. It stars Deborah Kerr, Yul Brynner, Jason Robards and Robert Morley. Deborah Kerr and Yul Brynner were paired again since they starred in The King and I in 1956, where he had an Oscar-winning performance. The Journey was shot in Metrocolor.
Major Surov (Yul Brynner) is the Russian commander at the Hungarian-Austrian border crossing. With the outbreak of the Budapest's airport is shut down and Diana (Deborah Kerr), along with other international travellers from U.S., Britain, Israel, and France, is forced to reach Vienna by bus. Along with them is a Hungarian dissident hunted by the police, Paul (Jason Robards).
In 1956 a group of passengers stranded during the Hungarian Revolution of 1956, at Budapest airport are taken in a bus towards the frontier with neutral Austria. From there they intend driving to Vienna.
A sick man in the back seat, who claims to be an Englishman called Flemyng, seems known to an aristocratic Englishwoman, Lady Ashmore, sitting in the front seat. The journey is difficult with diversions and roadblocks, some operated by Soviet troops and others by Hungarian insurgents. At a small lakeside town close to the Austrian border, the passengers are removed from the bus by Major Surov, the local Russian commander. After questioning them and impounding their passports, Surov orders they remain in the town's only hotel. He suspects the ailing Flemyng's passport is not genuine and develops a love interest in the attractive Lady Ashmore.
It emerges that Flemyng is a Hungarian insurgent whom Lady Ashmore, his lover, is smuggling to safety. Surov deduces both facts but does not act, hoping that Lady Ashmore will offer herself to him in exchange for safe passage into Austria. Speaking good English, which Surov claims to have learned in Canada, he uses the trapped passengers as a sounding board for his views, arguing that Russians are human too and questioning the imposition of Marxism by military force. However, with Flemyng getting weaker from what is revealed as an untreated gunshot wound, Lady Ashmore bribes a fisherman to take the two of them to Austria, across the lake under cover of darkness. Surov deduces what is happening and captures them both. After getting Flemyng treatment by an army doctor, Surov sends Lady Ashmore back to the hotel. The other passengers are furious that Lady Ashmore jeopardised their release with her selfish behaviour. A pregnant American woman warns Lady Ashmore very frankly what she should do to save them all.
Sniping by Hungarians has kept the Russian garrison on edge and a shot wounds Surov's beloved black horse. Unable to euthanise the horse himself, revealing a compassionate side to his nature, Surov orders a sergeant to kill the stricken animal. Lady Ashmore returns, dutifully, prompting Surov, in deep sorrow, to question if she returned willingly. When she truthfully says no, Surov releases Lady Ashmore. In the morning Surov orders the passengers leave, minus the arrested Flemyng, driving to a quiet spot where they can walk into Austria. As the party crosses the border, Surov turns up with the weakened Flemyng, who he releases to Lady Ashmore. As Surov watches the two disappear, Hungarian bullets kill him.
