Final answer:
The statement that 'Strangers on a Train' unfolds entirely on a train is false. The movie starts on a train but then moves beyond it to various other locations including Washington D.C., a tennis court, and an amusement park.
Step-by-step explanation:
The claim that Alfred Hitchcock's "Strangers on a Train" takes place entirely on a train is false. While the film opens with a pivotal scene on a train where two strangers, one of whom is a tennis player named Guy Haines, and the other a charming yet sinister man named Bruno Antony, agree to "exchange murders", the movie continues with a storyline that extends far beyond the confines of a train. The narrative follows both characters as the plot unfolds in various locations including Washington D.C., a tennis court, an amusement park, and Guy Haines' home, demonstrating that the train is simply the setting for the initial meeting between the main characters.
