The Parent Trap both versions, the 1961 version and the 1998 version. Watch the 1961 movie first then the 1998 remake.

You really need to pay attention to the girlfriend of the divorced father of the girls. Vicky his girlfriend, is pretty much the average American woman of today. BTW in 1998 version, the girls (Lindsay Lohan) biological mom is a Unicorn.

Vicky is a major con artist and bitch through out both movies.
