Robin Williams in talks to return for 'Night At The Museum 3'
Ben Stiller is already on board for the third adventure, which will be set in London
Williams appeared as Teddy Roosevelt in the first two films, which starred Ben Stiller as a museum security guard who discovers that the exhibits magically come to life at night. Stiller is already on board for the next instalment, which will be set in London and starts shooting next February (2014).
Shawn Levy, director of the first two movies, is returning too. Both of the previous films were big hits at the box office, with 2006's Night At The Museum grossing a shade under $575 million (£355 million) worldwide and the 2009 sequel, Night At The Museum: Battle Of The Smithsonian, taking around $413 million (£255 million).
Owen Wilson, Amy Adams, Ricky Gervais, Christopher Guest and Steve Coogan all took supporting roles in one or both of the previous movies, but at present it is unknown if any of them will be back for the third adventure.
Meanwhile, Williams is currently starring opposite Sarah Michelle Gellar in The Crazy Ones, a new US sitcom about a father-and-daughter-run advertising agency. The series premiered on US network CBS on September 26 and has been awarded a full 22-episode season after making a strong start in the ratings.
