MovieHole.net recently chatted with actor Timothy Spall, who portrayed Wormtail in Harry Potter and the Prisoner of Azkaban and Harry Potter and the Goblet of Fire revealed that he will be appearing in the last two films.
"Well I'm actually.... yes... I'm in the next one", Spall revealed. "And I'm also in the one at the end - I have a very big scene in that. I think they might be shooting two of them back-to-back - hard to know though, what with this writer's strike and all. They're shooting the penultimate one at the moment - which I have a brief appearance in it. I should be doing that soon."
The actor can currently be seen in the theaters in Johnny Depp's Sweeney Todd.
