I'm puzzled why Michael Keaton's Dogberry is so easily dismissed from the competition.
WHAT?!?That was one of my favourite roles in the movie! I love when Keaton does comedy. His fixation on the word "ass" was unforgettable for being one of the last things I'd expect in a Shakespeare play while also natural and hilarious.
There is a case for any actor doing Dogberry to go over the top. Still, Keaton was not only way over the top but he was he doing a different nationality than the other actors. And he reminded me of Beetlejuice and the morgue attendant from Night Shift. I imagine Keaton was hired because he has done wild comedic characters and directed to ham it up. But when looking at the performances in Much Ado About Nothing, the one that is questionable, regardless of who's responsible for it, is Keaton's Dogberry.
I gather Shakespeare wrote these clown roles that didn't fit very well because they were popular, but moved away from these standup routines/farcical skits as soon as possible. I've forgotten whether it was Will Kempe who Shakespeare disliked, or Kempe was the more restrained replacement he favored in later plays.
