Forummer diedye posted this piece of news from Empire:
Speaking at a special screening of The Dark Knight at London’s Imax cinema on Monday night, he [Ian McKellen] said: “Well, I haven’t had the contract yet but it’s everyone’s intention that I play Gandalf so yes, I will be returning to the role. Although it’s not until 2010, I’m very much excited about returning.
When asked about del Toro and the look of the movie, Sir Ian answered:
Well, if you’re not going to have Peter Jackson, who else can handle the job? To get an international film-maker of his standing who adores the original trilogy, well I don’t think you could possibly find a better replacement, I think the look will be very much as it was, Weta is still involved, it’s still the same workshops, the same designers, I’ll be there, Andy Serkis (now confirmed to return as Gollum) will be there and Peter Jackson will still be around – not that he’ll interfere too much – so it’ll seem like the old family is getting back together again.
So there you go, further confirmation of several things: no one has been officially cast yet (nothing is signed), Sir Ian and Andy Serkis are to return, everyone’s on board with Guillermo del Toro and the look of the movie is expected to be relatively similar to that of the trilogy. [Empire]
