Another older East German film that is very good is “The Rabbit is Me”.
And then of course, “Top Secret!”
HAIL, HAIL, EAST GERMANY
LAND OF VINE AND GRAPE,
LAND WHERE YOU’LL REGRET
ANY TRY TO ESCAPE
NO MATTER IF YOU TUNNEL UNDER
OR TAKE A RUNNING JUMP AT THE WALL,
FORGET IT THE GUARDS WILL KILL YOU,
IF THE ELECTRIFIED FENCE DOESN’T FIRST.
