John Tartaglia would be a fun Bert.
Dick Van Dyke was freaking BRILLIANT as Bert in the movie. His accent may not have been spot on, but they couldn't have made a greater choice for someone to play Bert.
Honestly, I would LOVE to see Barry Humphries as Dame Edna as Mary Poppins. No joke. Or at least as Mrs. Brill.
Also, I'd love to see Christian Borle as Bert, and for Gavin Creel to play him on broadway, but we should be thankful to have the wonderful Gavin Lee here as Bert on broadway right now.
