20th Century Boy (2009)

A young man in modern America, Victor, over-read and over-imaginative, believes himself to be a World War I veteran, injured in France, returning to the country in the Roaring Twenties. He's discovered wandering the train tracks by a young and impulsive 20-something girl named Jane, who soon befriends him and adopts him into her life. These two friends grow inseparable, and Victor soon becomes the envy of Jane's jealous and over-protective friend, Dean, and the object of her neurotic and pushy boss Faye's affection, much to her meek husband Walter's embarrassment. The film explores the effects this strange character has on those around him, as well as his struggle to reconcile reality with his illusions and the everyday monotony of modern life with his romantic visions of the past.
