Rebecca Hall, Penelope Wilton and Jemaine Clement have been added to the cast of Steven Spielberg's 'The BFG'.

The 68-year-old filmmaker - who will co-produce the film adaptation of the Roald Dahl children's story alongside Walt Disney Studios - has added the trio to Mark Rylance, Ruby Barnhill and Bill Hader for what will be Disney's first-ever Spielberg-directed film.

Spielberg said: ''In more than 40 years of making movies, I have been on the producing end of a number of films for The Walt Disney Company, but never as a director.

''It is a special joy to be in the director's chair as we start The BFG, alongside my long-time friends and film collaborators Kathy Kennedy, who introduced me to this project, Frank Marshall and Melissa Mathison.

''Together with them and Disney, there are many reasons why I am so excited about this joint venture.''

Meanwhile, Spielberg has also been tipped to work with Oscar-winning actress Jennifer Lawrence on a new Warner Bros biopic titled 'It's What I Do: A Photographer's Life Of Love And War'.

The duo are said to be in talks over the film, which is based on a memoir by Lynsey Addario and tells the story of a woman who goes into war zones in search of truth.
