David Thewlis, of Harry Potter and Wonder Woman fame, will play the Boss Man, while Himesh Patel will play Keith, an orphan who becomes friends with Maurice.
Gemma Arterton will play Peaches, who in the book is a rat who works alongside Dangerous Bean, the cult leader of the rat family.
The characters of The Mayor and Boss Man are not featured in the original text and it has been speculated the latter could be a new version of Dangerous Beans, meaning he would be a rat alongside Peaches.
