Matthew Vaughn's take on Marvel Comic's Thor is one of an epic tale taking place throughout Asgard (the home of the gods). Apparently, that epic scale is weighing on Vaughn, as he discussed in an interview with Metro International.

I've done the script and we're talking about it. But it's a huge logistical and financial burden for anyone. So the budget is like 300 million at the moment, so we're trying to reshape it and get it down.

Vaughn also shared his thoughts on X-Men: The Last Stand. "It was weird because I worked on it and I storyboarded a lot of it. I think given the amount of time they had to make the film, it was pretty good. My version would've been different, very different. Far more emotional, far more about the characters. My version would've been at least half an hour longer. I couldn't believe how short it was. I thought it was OK. It wasn't as good as X-Men or X2: X-Men United. It lost its soul."

Thor is scheduled to be released in 2009.
