How did WWII influence TV and movies (esp. in 40's)?

There was no TV.


Movies were all rah, rah Patriotic babble.


For a good movie that was probably the first to show the true face of WWII - even though no part of the War was actually shown - "The Best Years of Our Lives." 1946 - 10-11 Oscars.

the second world war was the first conflict to make use of colored film in the u.s., and was often used to film combat footage. Also cameras were somewhat successfully waterproofed, so cameramen could die on the beaches with foot soldiers during invasions. Newsreels were played before and after movies to let the public get a sense of what hell was.
