The Parent Trap (1961) starring Hayley Mills, Maureen O'Hara, Brian Keith and Joanna Barnes.
It's great and the remake is great (I forgot just how similar they are). I know people are just craaaaaaaazy about Mean Girls (and it is good), but I think The Parent Trap was Lindsay's shining moment.
One of the few moments that didn't end up in the remake.
I never went to summer camp - when you actually live in the area where other kids travel to go to camp, it doesn't really make sense.
I also think that it would have really stressed me out and I wouldn't have enjoyed it in the slightest.
