The Bunker (1981, 720p) - Anthony Hopkins as Hitler
"Downfall" was already posted on here twice, but apparently not "The Bunker". This is a made-for-TV movie which suffers from its lower budget, but which is almost made up for by the performance of Anthony "Hannibal Lecter" Hopkins, for which he won an Emmy.
BONUS MOVIE: I didn't want to post too many Hitler movies, but here's a satirical movie called "Look Who's Back" in which he comes back to life in modern days. Disclaimer: I haven't watched this!
