The latest casting news on the Avengers 2 claim actor Andy Serkis joins the star-studded cast of the upcoming superhero film. The motion-capture actor has confirmed his appearance in "Avengers: Age of Ultron" but did not reveal the part he will portray.

Andy Serkis, who did motion acting as Gollum in "The Lord of the Rings" and "King Kong," revealed in an interview with Variety that he will appear in the movie in addition to being the consultant of the film's motion-capture effects. Additionally, the 50-year-old actor will be portraying a role on "AoU" and "Star Wars: Episode VII."

"I'm playing a role (in both films). On 'The Avengers,' I've been working closely with Mark Ruffalo," Serkis teased. However, the Slanted report claimed that Andy Serkis stopped short in confirming whether his work with actor Mark Ruffalo is related to the Hulk.

The actor remains tight-lipped on whether his appearance in the film will be physical or motion-capture. At the moment, Marvel has not yet clarified as well how the villain robot Ultron will appear on the film or it will be a new character that requires detailed effects.

Andy Serkis is famous for his motion-capture acting after portraying characters like Gollum in the "Lord of the Rings" films and the most recent one as Ceasar in the "Dawn of the Planet of the Apes" film.
