Andy Serkis has confirmed he will appear in 'Avengers: Age of Ultron'.

The 'Star Wars: Episode VII' actor - who is already working on the sequel as a consultant through his motion-capture company The Imaginarium' - has revealed he will also be making an appearance in the film.

He told Variety: ''The Imaginarium is the performance capture consultant and I'm playing a role in both Avengers and Star Wars.''

However, when asked if his face will appear in the Marvel follow-up, he explained: ''I'm not at liberty to mention. But it's all the same to me. I've never drawn a distinction when playing a role, whether it be live action or performance capture.

''Acting is acting. It's just basically what you wear to the set that's different.''

The 50-year-old actor also spoke about working closely alongside Mark Ruffalo after he was hired to assist the 46-year-old with his portrayal of The Hulk for the comic book blockbuster.

He said: ''On Avengers, I've been working closely with Mark Ruffalo.

''There are tools and ways of working with an actor that makes them feel that they own the character, and a character the size of the Hulk needs ownership, which Mark has now.''

'Avengers: Age of Ultron' will be released in the UK on April 24 2015, while 'Star Wars: Episode VII' will be released in December 2015.
