Bad Casting Choices in the Movies and Television

I always thought Goodman in his prime (late 80s/early 90s) would have been the best Ignatius.. but tomato/to-MAH-to i guess.
Goodman would have made the movie about himself. Folks who never read the books would just think it was a silly John Goodman vehicle movie.

It would need to be an unknown actor - so the move would be about Ignatius.

There was a guy playing Ignatius on stage in the 90s who was perfect.
