Different Movies, Same Title

They've been making movies for what, about 150 years now? Some length of time that should make it no surprise some titles have been used more than once. 

Dark City (1950 and 1998)

Charlton Heston gambling film noir becomes Kiefer Sutherland science-fiction movie marred by an over-explaining opening narration.

Diary of the Dead (1976 and 2007)

Ruth Rendell mystery starring Garry Marshall's favorite actor Hector Elizondo becomes the first in a looooong step down for the once visionary horror filmmaker George A Romero.

Gung-Ho (1943 and 1986)

War film based on the battle for Makin Island becomes Ron Howard comedy about the wacky differences between US and Japanese culture in a car manufacturing plant.

Hannibal (1959 and 2001)

Historical film about the famous crossing the alps with elephants becomes the too late, brain eating sequel to the elegant Silence of the Lambs.

Pretty Baby (1950 and 1978)

Romantic comedy about a woman who somehow woos a man by pretending a toy doll is a real baby she has named after him becomes unbelievably exploitive film about child prostitute featuring way too many nude shots of the 12 year old actress (I've read the DVD versions zoom the picture in on these scenes but I haven't re-watched since seeing the film on VHS years ago). The 1950 film features Lucy Ricardo's landlord, Fred Mertz.

Superman (1948 and 1978)

Early serial edited into a feature film becomes the beloved Christopher Reeve classic. Not quite two different movies with the same title but still not quite a re-make.

The Edge (1977 and 1997)

Soft-core skin flick starring Emmanuelle actress becomes David Mamet penned story about business men lost in the woods fighting a bear.
And that's not Brian Dennehy but Anthony Hopkins on the poster.
