The Uninvited (1944)
Stylish, well acted and with what was then cutting edge technology for special effects.
The Vampire Bat (1933)
Creepy and very well acted by top actors of the day.
The Innocents (1961)
Is the haunting real or in the mind of the haunted. You must decide. The wonderful Deborah Kerr is marvelous in this!
The Others (2001)
A classic haunting with a twist of an ending. Artfully shot and very well acted.
Easy to forget how frightening this movie was when it came out. Still holds up with its wonderful blend of humor and horror.
Burnt Offerings (1976)
I was recently also given a recommendation to see this, but I haven't yet seen it. It is rated PG, which bodes well for my list. :)
All these movies can be rented through Netflix.
