Andy Serkis has confirmed he will be appearing in the Avengers follow-up Avengers: Age of Ultron.

The 50-year-old Star Wars: Episode VII actor has revealed that he will be making an appearance in the Avengers sequel, as well as working as a performance consultant on the movie with his motion-capture company The Imaginarium.

Speaking to Variety Serkis said: ''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.''

He added: ''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 on April 24 2015, while Star Wars: Episode VII will be released in December 2015.
