You've picked some good ones. I haven't read The End of Eternity for probably 25 years, but it's still fairly fresh in my memory. I'd put that very high on my list of time travel books/movies, if not number one. I think I'll hunt down a copy and read it again.
A Sound of Thunder is very good as well. I just re-read that one a few months ago while revisiting a couple of Bradbury short story collections.
The movie that comes to mind is rather predictable and campy, but I liked it. The Final Countdown. The U.S.S Nimitz gets sucked into a time vortex, arriving off Hawaii on the Eve of the Pearl Harbor attack.
There was a short-ish story I once read where we start with a young guy (call him #1) who sees a circular portal into another world.
Then another guy appears (call him #2) saying he's a later version (that is older) of #1 and saying not to go through the portal.
Then another guy appears (call him #3) saying he's a later version of #2 and telling #1 NOT to go through the portal.
There's a bit of a scuffle and #1 gets pushed through the portal.
Anyway, the bottom line is that we follow #1 as he eventually becomes #2 and then #3 and eventually #4 (who I didn't mention because it's a bit of a surprise).
Does anyone know the name of that story and the author?
A friend of mine just sent me a message saying: "I quite like Timeline by Michael Crighton, if only for his explanation of how the Young's Slits experiment works at low light levels because someone in a nearby parallel universe is also doing the experiment."
I'd forgotten about Timeline, but it is a good book.
Primer is based on a great premise, but the movie could have been so much better. Perhaps given a bigger budget? The concepts will take you a few minutes to grasp, and it will definitely make you think. Given that, it is available on Netflix if you have that, unfortunately it is only on DVD and not instant queue.
Speaking of Michael Crichton, one of his best and often unmentioned works is Sphere, of which they made a film starring Dustin Hoffman. As with all book adaptations, the book is better, but the movie is still entertaining.
