Oldman and Serkis at Apes premiere
Gary Oldman and Andy Serkis weren't having any monkey business at the premiere of Dawn Of The Planet Of The Apes.
The British actors joined co-stars including Keri Russell and Jason Clarke on the red carpet at the world premiere of the new film in the US, but kept tight-lipped about all non-ape related topics.
When asked about the furore over his recent comments to Playboy magazine, Gary simply made a zipping motion over his lips and smiled.
And Andy was not giving anything away about his role in JJ Abrams' new Star Wars film.
Asked what role he is playing, he teased: "I can definitively say I'm not playing Yoda, I'm playing someone else. I would be shot [if I told you who]."
The Hobbit star and expert in motion capture plays ape Caesar in Matt Reeves' new film, the eighth in the Planet Of The Apes franchise and the second instalment in the current reboot series.
Andy said: "This movie is all about empathy, it's all about understanding the other, and Caesar is an outsider to both worlds, to both species in a way. He is placed in that position of trying to avoid that conflict.
"I do think it is a movie for our times, it is against any form of fundamentalism or absolutism, it is about understanding the other and not being prejudiced."
Keri Russell admitted the premiere would be the first time she has seen what the apes look like on the big screen, as they were created using motion capture and CGI special effects.
She said: "This is the first for a lot of us, with sound and visual and the apes actually in place. We did most of our acting just imagining there were apes everywhere. I'm not sure yet - let me go see how it worked out!"
The sequel to 2011 film Rise Of The Planet Of The Apes, there is a third film planned in the series, but the stars were not giving anything away about whether their characters will be returning.
Gary joked: "I wouldn't mind coming back as an ape. Maybe I could do that - try some of the motion capture!"
Jason Clarke said: "I'd love to return for the third one. I really wanted to experience working with Andy and motion capture. I think it's important to stay up to date with that stuff as an actor. To have these experiences that are challenging and at the forefront of what movie making is doing at the moment."
Dawn Of The Planet Of The Apes is scheduled for release on July 17, 2014.
