Forget 'Meatballs' or 'Wet Hot American Summer.' Everyone's favorite summer camp movie seems to be 'The Parent Trap,' where Hayley Mills goes to camp and instead of finding mosquitoes and poison ivy finds the identical twin sister she never knew she had. Together, they scheme to reunite their divorced parents by switching places after camp.

Released 50 years ago this week (on June 21, 1961), the live-action Disney film has remained a childhood favorite for half a century, and it proved influential in ways probably no one associated with it would have imagined.
