Sigourney Weaver has been added to the cast of 'A Monster Calls'.
The actress will appear alongside the likes of Felicity Jones and Liam Neeson in the film, which is a feature adaptation of the award-winning fantasy novel by Patrick Ness.
The movie is to be directed by Spaniard Juan Antonio Bayona, who performed the same role for the 2012 drama 'The Impossible'.
The film centres on a young boy who tries to cope with bullying at the hands of his classmates, as well as his mother's terminal illness, by escaping into a world that allows him to put his everyday troubles to one side.
The Hollywood Reporter says Weaver, 64, will play the role of the boy's grandmother, while Jones is to play the mother and Neeson will star as the tree monster who helps guide the boy in the fantastical world he comes to inhabit.
The film is set to be released in the US on October 14, 2016.
Meanwhile, Weaver recently passed up the opportunity to appear in the much-anticipated 'Expendabelles' film, which is a spin-off of the popular 'Expendables' franchise starring Sylvester Stallone and Jason Statham.
