Sir Patrick Stewart is set to play a ''different version'' of Charles Xavier in 'Wolverine 3'.

The 75-year-old star - who's appeared as the professor in the superhero film series - has revealed his character will be markedly different from his previous on-screen appearances in the new movie.

He explained to Digital Spy: ''There is, I am told, a 'Wolverine' movie in development that would include Charles Xavier, but a very different Charles Xavier from the one we have seen before. And I don't quite know what that means, but I'm very excited about it.

''He's a terrific character, but I am looking forward - if what I've been told is true - to a different version of Charles. We shall see.''

Last month, Hugh Jackman - who stars as Wolverine - asked fans what they want to see happen in his final outing as the superhero.

Hugh took to his Twitter account to canvas fans' opinions about what should happen to Wolverine.

He wrote: ''My last time putting on the claws. What do you want to see happen? 50 words or less. I'll read as many as I can. (sic)''
