Poor Shemp- your name is forever associated with the worst era in Three Stooges history (even though plenty of good shorts came out of that era), and when you passed away they had to use a stand-in to complete the four shorts owed to Columbia Pictures.
These "fake Shemps" give movie and TV productions a cheesy feel, causing viewers to wonder why the studios didn't just replace the actor with somebody else, or simply write them out of the script, for the sake of production value.
Take the Sopranos for instance- actress Nancy Marchand, who played Tony Soprano's mom, passed away in 2000 and left the show with a major gap in their lineup.
