Andy Serkis is indeed going to be participating in the upcoming Peter Jackson motion capture flick Tintin. According to Variety, Steven Spielberg is also going to be directing one of the three Tintin films in production at DreamWorks which Serkis will also participate in.
The film is based on Georges Remi's Belgian comic strip of the same name. While Serkis has signed on as the quote-unquote star of the films, DreamWorks is staying mum about which character he will actually be playing.
The film will begin shooting in September, unless, of course, the strike is still going on at that time.
