Who would you pick as the person who was the best actor/director/producer/writer based on body of work. They should have been involved in 3 of the 4 titles for this list.

In no specific order:
Jack Webb
Sheldon Leonard
Ozzie Nelson
Bob Sweeney
Jerry Paris
Peter Bonerz
Alan Alda
Penny Marshall

I'll go with Ozzie Nelson topping the list.

Gotta go with Sheldon Leonard. His influence is huge - it's in every show from MTM, Garry Marshall, Witt-Thomas, Danny Arnold. Cheers brought him in as an actor when he was about 80, Frasier copied his erudite gangster after he died, and Chuck Lorre named Sheldon and Leonard after him.

I didn't realize he had is hands in so many things.

Sheldon Leonard #1

Alan Alda #2

Carl Reiner
Garry Marshall
Aaron Ruben

Aaron Ruben makes it in three of the four, but he was also an actor in a Gomer Pyle episode. He plays the guy running the recording session when Lou-Ann makes a record. We see him through the soundproof glass yelling at Sgt. Carter because she's so bad and wasting his time. He does it well and is funny.
