Kenneth Mars, a Mel Brooks collaborator who played a Hitler-worshipping playwright in “The Producers” and an earnest police inspector with a malfunctioning artificial arm in “Young Frankenstein,” has died. He was 75.

In a statement Monday, Mars family said the actor died Saturday of pancreatic cancer at his home in Grenada Hills.

In Brooks’ 1968 romp “The Producers,” Mars co-starred as Franz Liebkind, a Nazi enthusiast whose play, “Springtime for Hitler,” is the basis for a scheme by two conniving showmen (Zero Mostel and Gene Wilder) to bilk investors by putting on a surefire Broadway flop.

One of my favorite characters in any movie…ever.
