'Avengers: Age Of Ultron': Andy Serkis Helping Mark Ruffalo With Hulk Mo-Cap

Most actors would be lucky to work on one of the biggest releases in a given year. Andy Serkis will be involved with two in 2015. Mark Ruffalo has revealed that Serkis is helping him on Avengers: Age of Ultron, before Serkis heads over to do Star Wars Episode VII. Hit the jump for more details.

The wording suggests that Serkis isn't playing a new character, but rather that he's helping Ruffalo with his mo-cap scenes as the Hulk. As you'll recall, Ruffalo didn't just play Bruce Banner in The Avengers. He also played the Hulk, with the help of green screens and skintight suits decorated with awkward dots and balls, and he'll do the same for Avengers: Age of Ultron.

While we had no complaints about Ruffalo's performance in the last film, it can only help Ruffalo to get some additional pointers from Serkis for Age of Ultron. Ruffalo's a great actor, but Serkis is a mo-cap legend. He's earned heaps of praise for his work on films like Lord of the Rings and the Planet of the Apes prequels.

How much work Serkis is doing on Avengers: Age of Ultron is unclear. Both it and Star Wars Episode VII are shooting in London, which helps explain how Serkis is able to pitch in with Avengers even as Star Wars gets underway.

In the meantime, keep an eye on Ruffalo's Twitter for more Avengers dirt. He's been tweeting up a storm from the set, posting cute photos of his co-stars and such.

Avengers: Age of Ultron, starring Ruffalo, Robert Downey Jr., Chris Evans, Chris Hemsworth, Jeremy Renner, and Scarlett Johansson, opens May 1, 2015. Star Wars Episode VII follows a few months later on December 18, 2015. Before any of that, catch Serkis working his mo-cap magic again in Dawn of the Planet of the Apes on July 11, 2014.
