'Thor 2' is being re-written by Oscar nominated Robert Rodat, who wrote 'Saving Private Ryan'.
The Hollywood scriptwriter has been brought in by Marvel to re-write The Script, a first draft of which has already been submitted by Don Payne.
The comic book company has a policy of always getting a second writer to look over and polish scripts which have initially been submitted.
Tom said: "All I know about 'Thor 2' is that we're supposed to film it in London in the summer and that it's being directed by Alan Taylor."
Rodat, is best known for scripting Saving Private Ryan - for which he received an Oscar nomination - but he has also worked on films including 'Fly Away Home' and 'The Patriot' as well as overseeing alien invasion TV Drama 'Falling Skies'.
