The film will feature special guests Dan Castellaneta, David Cross, Stephen Hawking and Brittany Murphy, and according to DVDActive:
In Futurama's latest and most tentacle-packed epic, space itself rips open, revealing a gateway to another universe. But what lies beyond? Horror? Love? Or maybe both, if it happens to contain a repulsive, planet-sized monster with romantic intentions! Nothing less than the fate of human and robot-kind is at stake as the Futurama crew takes on The Beast With A Billion Backs.
Now all we need is an official Futurama Lego set, and we'd be in heaven (or maybe robot hell).
