A Hard Day's Night. Because it's very funny, and the concert segment at the end will remind me of the best of what I gave up when I left western civilization behind.
Gone with the Wind. Because it's got romance and struggle and war and reconciliation and just about every experience known to man.
The Godfather. So I won't get rusty on all the memorable quotes: "You have to answer for Santino." "Leave the gun. Take the cannoli." "Make him an offer he can't refuse." "Don't ever take sides with anyone against the family." "Today I settle all family business ..."
That's Entertainment. Because I can't pick just one MGM musical.
Butch Cassidy and the Sundance Kid. Because why not be stranded with the two coolest guys ever?
