Gemma Arterton has signed up for new film Absolutely Anything, according to reports.
The Wrap said that Sherlock star Benedict Cumberbatch was also in talks about joining the film.
Directed by Terry Jones, Absolutely Anything will feature voice-overs from Monty Python stars Jones, Terry Gilliam, Michael Palin and John Cleese.
Comic star Robin Williams will also do a voice-over for the film, about a teacher who discovers he has magical powers.
Filming is expected to begin next year, with Jones directing from a script he co-wrote with Gavin Scott, The Wrap said.
Gemma's recent credits include Clash Of The Titans and Byzantium while Benedict was recently cast as Beatles manager Brian Epstein in The Fifth Beatle.
