The Fly - Jeff Goldblums version
Invasion of the Body Snatchers
The 1978 version of "Invasion of the body snatchers" along with J. Goldblums 'The Fly' is the one I grew up with. Both very good movies. Here is a short list of a few more favs. Some have some serious cheese factor going for them, but I still love watching them.
Bunny Lake Is Missing (1965) Jodie Foster's "Flightplan" (2005) was basically a remake of this movie.
Bad Day At Black Rock (1955)

Nate and Hayes (1983) This is also known by the title "Savage Islands", was one of Tommy Lee Jones earlier leading roles.
Snowpiercer (2013) There is a theory going around that you can find on Youtube that this is a non-official sequel to Willy Wonka And The Chocolate Factory (1971).
I'm a little bit of a Moviephile and could probably name about 50 more movies I could just watch over and over and over but I'll stop here.
