Last week, TrekToday reported that the Harcourt Fenton Mudd (Rainn Wilson) character would be seen “multiple times” on Star Trek: Discovery, and now we know how much we will see of the popular original series character.
According to IMDB, expect to see Mudd for more than half the season. They have Wilson listed as appearing as Mudd for nine episodes. This will be in a season which will feature fifteen episodes.
Don’t be surprised if the number changes though as IMDB is a work in progress and is often amended.
