Mark Hamill, aka Luke Skywalker, will play the voice of psychotic bad guy The Joker in upcoming Batman game Arkham Asylum, co-publisher Eidos has confirmed.

Hamill reprises his role from The Animated Series, as does Kevin Conroy, who's set to lend his vocal chords to the gruff tones of Batman himself.

Developed by London-based developer Rocksteady Studios, the brains behind 2006's PS2 and Xbox title Urban Chaos: Riot Response, Arkham Asylum features an original story plucked from the mind of Animated Series writer Paul Dini, and looks like it could be really rather good. We're promised a "Gothic, moody and extraordinarily detailed setting" and a "unique, dark and atmospheric adventure". Nice.

Batman: Arkham Asylum is due out summer next year on Xbox 360, PlayStation3, and PC.
