According to TV Line, [Rainn] Wilson has been cast to play a younger Harry Mudd in Star Trek: Discovery.
Mudd is not the worst character in all of Star Trek (cough Vic Fontaine cough), but he is at best a slapstick idiocy that it’s hard to see working in a more modern TV series. Maybe a gritty take would be interesting, but that would be hard to link into TOS. Rainn Wilson doesn’t strike me as the best casting either – his most famous role (Dwight in The Office) is more famous for deadpan humour than the sort of scenery chewing slapstick of Mudd.
Putting this into the ‘uh oh’ column.
