Time Travel: Alternate Realities and Wormholes

As far as Time-Travel/Alt-Reality/Wormhole Movies go, Donnie Darko has to be one of the best. There are so many out there it is hard to say which is the very best. I am starting a list. Please feel free to add to it. I am hoping there is one out there I have yet to see.


The List:

Back to the Futures - (we all know these)
Donnie Darko - (Grandma Death is the best)
Butterfly Effect - (a little too Hollywood but still ok)
2001 A Space Odyssey - (an oldie but a goodie)
12 Monkeys - (one of the best)
Bill and Ted's Excellent Adventure - (gotta love it)
Ground Hog Day - (can cause yawning)
The Jacket - (wow! what a movie)
Contact - (with Jodie Foster - its also about alien contact)
Planet of the Apes - (can't leave this one out)
The Terminators - (classic fun)
Time Bandits - (80's fantasy adventure - great one)
The Family Man - (feel good kinda thing - warm and fuzzy)
Frequency - (with James Caviezel & Dennis Quaid -excellent)
Millennium - (Cheryl Ladd & Kris Kristofferson - loved it)
Slaughterhouse Five - (Kurt Vonnegut novel put to film)
Click - (Adam Sandler rules - another feel good but better)
Peggy Sue Got Married - (silliness but still fun)

There are more I am sure I'm forgetting. Please add to it if you can.
