I only remember a small scene from this movie I saw.
This girl is in the shower, and this guy that's staying at her house, I think he is like a stranger or something. But anyway the shower is really big and so they don't notice each other for a minute then when they do they both scream really really loud. There was also a teenage daughter who like the stranger I think.

I also was thinking about this other movie that I saw and can't remember what it was this lady was held captive in her own house and someone came to the door needing a check for something and when she filled it out she put help on the bottom of it, but the bad guy caught her and made her pay in cash.
Any info would be great. Thanks

The first one sounds like Crush with Alicia Silverstone as the teenage girl. Can't help on the second one.

Cops and Robinsons has a "shower scene" like that... that one has Chevy Chase...
