1) Peter Serafinowicz
While you may not recognize his face, unless you’re an avid Guardians Of The Galaxy fan, Peter’s resume is a who’s who of geekdom. Currently, he is appearing as the title character for Amazon’s action-comedy series The Tick. He has voiced many roles in animated series like Archer and Neo
As for Doctor Who, Serafinowicz voiced the character of The Fisher King in 2015 for the Peter Capaldi story Before The Flood.
However, it is his contribution to Star Wars where his voice is probably most recognized. While the face and movement belonged to Ray Park, Darth Maul’s voice was provided by Peter in The Phantom Menace.
