"Get me out of this stinkin' fresh air!"

One of Disney's most fondly remembered live action comedies, this pleasant film stars Hayley Mills as twins, separated by a divorce when they were young, who meet accidentally at summer camp. They become fast friends and plot to switch places so they can each meet the other half of the family. The special effects required to get Hayley Mills to appear on screen with herself raised some eyebrows at the time.
