There will be the occasional high-impact drama that usually has the same villains. Some example plots: Jews, communists, or both are infiltrating the country, and want to overthrow the noble dictatorship. OR, in a remote part of, say, Transylvania (propaganda, equating Jews to vampires!), "Jewhunters" uncover a secret community of fugitive Jews, but get trapped and have a harrowing adventure. OR, Jewish terrorists assassinate the American president and blame it on Germany, leading to possible war!
Very possible. I can see a German James Bond, say Johannes Bauer, hunting Sov, Amerikan, & Britische spies, & their Jew saboteur-collaborators, & being very successful in Occupied Europe. On the other side of the "Berlin Wall" (so to speak), Quiller (who started as a Nazi hunter, recall) would be bigger.
Science fiction would be less popular.
You might see alien invasion movies, and maybe adventures in the Hollow Earth or the Hollow Moon, but I think they might be officially discouraged, usually.
Don't forget the U.S. attitude in the '50s: alien invasion & mind control as metaphor for attack by Soviets. The "hidden Red" of the U.S. would be the "hidden Jew", the "enemy within". "The Thing", "Invasion of the Body Snatchers",
The Puppet Masters, all products of Jewish infiltration & domination...
Destination Moon would have heroic Germans (not called astronauts, natch--or under the same title

) beating the evil Jew-sponsored Amerilkaners.
Superman would be banned (& possessing copies'd probably get you jail, since he was created by Jews & published by Jews


), tho there'd probably be a German clone (complete with SS thunderbolts on his chest!
Oberst Deutchmann?), & he'd probably be created by the government. (Think
Justice Machine.)
I also think there's be much more acceptance of high fantasy & magic in pop culture, since it's more/less endorsed by the government: something like "Dresden Files" or "Buffy", where the hero actually uses magic, but is mainstream, like "Witch Hunt" (the Dennis Hopper film). Or where astrology solves cases.
