Warner Bros. has released a new trailer for Wally Pfister's directorial debut Transcendence.  The sci-fi film stars Johnny Depp as Dr. Will Caster, a researcher at the forefront of Artificial Intelligence science who becomes intimately entwined with his research after an attack by the anti-technology terrorist group, R.I.F.T.  Whereas the first trailer was a quick rundown of the film's premise, this second trailer shows things down a bit to give us a good look at what Pfister has put together.  The pic looks like a tense and trippy science-fiction thriller almost in the vein of Videodrome, and I'm very curious to see to what extent Pfister explores the larger implications of tech-growth in our digital age.  My only qualm with this trailer is that it looks like it might be giving away too much of the story, but hopefully Pfister is keeping further surprises under wraps.

Hit the jump to watch the trailer.  The film also stars Paul Bettany, Rebecca Hall, Kate Mara, Cillian Murphy, Clifton Collins Jr., and Morgan Freeman.  Transcendence opens in 2D and IMAX on April 17th.

Here's the official synopsis for Transcendence:

Dr. Will Caster (Johnny Depp) is the foremost researcher in the field of Artificial Intelligence, working to create a sentient machine that combines the collective intelligence of everything ever known with the full range of human emotions. His highly controversial experiments have made him famous, but they have also made him the prime target of anti-technology extremists who will do whatever it takes to stop him. However, in their attempt to destroy Will, they inadvertently become the catalyst for him to succeed—to be a participant in his own transcendence. For his wife Evelyn (Rebecca Hall) and best friend Max Waters (Paul Bettany), both fellow researchers, the question is not if they can…but if they should. Their worst fears are realized as Will’s thirst for knowledge evolves into a seemingly omnipresent quest for power, to what end is unknown. The only thing that is becoming terrifyingly clear is there may be no way to stop him.
