Peter "The Witch" Serafinowicz is an English actor, voice actor, comedian, and writer. He played Pete in Shaun of the Dead and Garthan Saal in Guardians of the Galaxy. He currently stars as the title character in the live-action adaptation of "The Tick" alongside Blank Check co-host Griffin Newman.
Peter was a guest for the Talking Maul live episode of Blank Check. Peter was the voice of Darth Maul in Star Wars: Episode I – The Phantom Menace, so while filming for "The Tick" Griffin got the opportunity to invite him on the podcast - finally an actor from The Phantom Menace trilogy appears on the show!
It turns out that his vocal performance was recorded separately from any other aspects of the production (the movies were famously heavy on ADR) and the entirety of the role is less than three lines. Thusly the episode is mostly an extended bit about how "method" Serafinowicz went for a very small role.
