The man from earth jumps out as being a similar kind of sci fi, its really an under appreciated genre. Like an awesome episode of the twilight zone but very fleshed out like these two. Anyone got anything good?
shareMoon is another good one which is also in the reccomendation box for this one. Sci fi movies with great starting concepts are just the best.
shareGood sci-fi should always start with an interesting concept. Interstellar coming out soon is meant to have a very intelligent script.
shareTotal Recall and Jacob's ladder are similar. Maybe they are their own genre.
Life is like Wikipedia: There are no Facts, Just Popular Opinion
Man facing southeast, which this movie ripped off.
shareIn terms of asking the question "is it real, or is it a hoax?" another good sci-fi movie is Safety Not Guaranteed.

The Man from Earth (2007)
shareStarman is another one a bit like this to I think.

If you liked K-PAX but somehow haven't seen 12 Monkeys that should be very high on your list.
Note that this is more if an fyi in general than directed at this ancient post.
