Hider in the House (1989)

The thought of Gary Busey living in your attic is enough to scare anybody who's caught an episode of Celebrity Apprentice (or Google image searched him lately). But this premise takes an even more sinister turn in Hider in the House (1989), starring Busey as Tom Sykes, a deranged stalker who becomes obsessed with Julie Dreyer (Mimi Rogers), the wife of the couple who lives in the house where he (you guessed it) has been hiding out in the attic. Sadly, Mimi's magnificent mams don't make an appearance here, but Rebekah Armstrong's do during an adulterous hotel-room encounter. Talk about a house-warming present!
