Seth Green, who appeared in the Jessica Alba-starring Idle Hands and voices Family Guy's Chris Griffin, is one of the many A-list celebrities lending his vocal talents to BioWare's Xbox 360 sci-fi RPG Mass Effect.

In the game, Green portrays Joker. Other celebrities and their respective roles include Millenium protagonist Frank Black, Lance Henriksen himself, as Admiral Steven Hackett, Pitch Black veteran Keith David as Captain David Anderson, and Star Trek: The Next Generation hottie Marina Sirtis as The Matriarch.

To celebrate their addition to the cast, Microsoft released three videos, one of an informational interview with Green, the second featuring amusing outtakes from Green's sessions, and the third questioning Henriksen, David, and Sirtis about their efforts.
