A scooper at AICN has sent in the following:
"I'm currently working at the bradford international film festival in the UK, and tonight we had Simon Beaufoy, screenwriter of Slumdog Millionaire doing a screentalk. Anyway, he dropped a bit of a scoop, he's been employed to write the script for "wolverine 2. He commented that while he was apprehensive about the project (claiming to not even know what a Wolverine was!) his agent pursuaded him to take it on. He clarified that working on a film thats successor has yet to be finished was a strange experience, and one that he wasn't sure he was comfortable with. Anyway, I read your site everyday and figured Id send this interesting little tidbit over -- Adam
Ain't It Cool does not say if they've had prior dealings with this scooper or why they give the note enough credence to run with a story, so consider this an unsubstantiated rumor at this point.
