Shaun Parkes as Captain Zach
Definitely one of the coolest episodes in David Tennant’s first season as the Doctor, “The Impossible Planet” and “The Satan Pit” boasted a great cast and the pure sci-fi goodness that so many of us love. The leader of the crew was Captain Zach, a character who is a bit rough around the edges but strong and capable. The TARDIS is in dire need of some minority companionship, and Shaun Parkes is great as Captain Zach. Make it happen, Moff!
