YMMV / Er Ist Wieder Da

• Angst? What Angst?: Hitler insists that he's fine going at the modern world alone. However, he spends the early part of his second day there meekly trying to find his contemporaries on the off-chance they got sent forward in time as well.
• Older Than They Think:
  • The concept of Hitler coming to the present-day and attempting to win crowds to him again (not the You Cloned Hitler! or Apocalypse Hitler variants) was examined as far back as the original The Twilight Zone in the 1963 episode "He's Alive". Both feature Adolf Hitler reappearing in the present-day and attempting to woo followers to his cause, along with a Downer Ending that implies Hitler will continue his hateful crusade. The primary difference is that Look Who's Back shows Hitler jumping through time somehow and takes a direct hand in drawing people into his ideology. "He's Alive" simply showed Hitler as a sort of phantom that helps another man woo people into Nazism and stays out of sight to direct his hateful activities.
  • Ray Bradbury wrote a similar short story in the '70s called "Darling Adolf," which features an actor playing Hitler in a biopic shooting on location in West Germany. The actor becomes a bit too engrossed in his role, persuading the director at one point to restage a Nuremberg rally with a literal cast of thousands, while finding that modern Germans are disturbingly receptive to a revival of Nazism. While Hitler doesn't actually appear in the story, per se, the message is very similar to both Look Who's Back and the Twilight Zone episode - that the appeal of fascism, if hidden, remains as strong as ever.
