"UGO reports that Dylan Baker confirmed last night at a Trick 'r Treat screening in New York that he'll be back as Dr. Curt Connors in director Sam Raimi's Spider-Man 4.
There's been a lot of speculation that Connors will finally become The Lizard in the fourth installment, but Baker said that he had just gotten his first call about the film that very day.
The site says that Trick 'r Treat director Michael Dougherty ribbed him about 'just appearing in the background,' and Baker said that's what he'd be doing. It is, of course, unknown if Baker can say anything at this point, so it might be too early to take that as a fact.
Columbia Pictures is planning a May 5, 2011 release in conventional and IMAX theaters."
