The Terminal

Viktor Navorski (Tom Hanks) arrives at JFK International Airport, but finds that he is not allowed to enter the United States. While he was en route to the US, a revolution was started in his home nation of Krakozhia. Due to the civil war, the United States no longer recognizes Krakozhia as a sovereign nation and denies Viktor's entrance to the US. Unable to leave the airport or return to Krakozhia, Viktor instead lives in the terminal, carrying his luggage and a mysterious Planters peanut can.Customs and Border Protection (CBP) Head Frank Dixon (Stanley Tucci) wants Navorski removed from the airport. Navorski collects money for food by retrieving vacant baggage trolleys for the 25-cent reward from the machine, until Dixon prevents this. He then befriends a catering car driver named Enrique (Diego Luna) who gives him food in exchange for information about a female Customs and Border Protection officer (Zoë Saldana), who Enrique is infatuated with. With Viktor's help, Enrique and Dolores eventually marry each other. He meets flight attendant Amelia Warren (Catherine Zeta-Jones), who asks him out to dinner, but he tries to earn money in order to ask Amelia out instead. He finally gets an off-the-books job as a construction worker at the airport earning $19 an hour.Viktor is asked to interpret for a desperate Russian man with undocumented drugs for his sick father. Viktor claims it is "medicine for goat," barring the drug from confiscation and resolving the crisis. Under pressure and the watchful eye of the Airport Ratings committee, who is evaluating Dixon for an upcoming promotion, Dixon has a falling out with Viktor. Though Dixon is advised that sometimes rules must be ignored, he becomes obsessed with getting Viktor ejected from the airport. An airport janitor, Gupta Rajan (Kumar Pallana), exaggerates the "goat" incident to his fellow co-workers and as a result, Viktor earns the respect and admiration of all of the airport staff.One day, Viktor explains to Amelia that the purpose of his visit to New York is to collect an autograph from the tenor saxophonist Benny Golson. It is revealed that the peanut can Viktor carries with him contains nothing more than an autographed copy of the "Great Day in Harlem" photograph. His late father was a jazz enthusiast who had discovered the famous portrait in a Hungarian newspaper in 1958, and vowed to get an autograph of all the 57 jazz musicians featured on the photograph. He succeeded in obtaining 56, but died before he could finish his collection.A few months later, the war in Krakozhia ends, but Dixon will still not allow Viktor to enter the United States. Amelia reveals that she had asked her 'friend' actually a married government official with whom she had been having an affair to assist Viktor in obtaining permission to travel within the US, but Viktor is disappointed to learn she has renewed her relationship with the man during this process.To make matters worse, Dixon needs to sign the form granting Viktor the right to remain in the United States, but refuses. He instead blackmails Viktor into returning to Krakozhia, or he will have Enrique fired for allowing Viktor into the restricted food preparation area and deport Gupta back to his native India, where he is wanted for assaulting a corrupt police officer. Upon hearing this, Gupta runs in front of Viktor's plane and asks Viktor to go anyway. The plane is delayed, giving Viktor enough time to go into the city and obtain the autograph. With the blessing of the entire airport staff, Viktor leaves the airport after receiving a uniform coat from a U.S. Customs and Border Protection Assistant Port Director and hails a taxi. Dixon, watching Viktor leave the airport, decides not to pursue him. As Viktor prepares to take the taxi to a Ramada Inn where Benny Golson is performing, he observes Amelia exiting from a cab, where she gives him a wistful smile. He has a short conversation with the cab driver, telling him how to avoid traffic on the way to the hotel and that he is from Krakozhia. The driver tells Viktor that he is from Albania and arrived earlier that week. He attends the show and collects the autograph, finally completing the collection. Afterwards, Viktor leaves and hails a taxi, telling the driver, "I am going home."
