Rainn Wilson and Joely Richardson have signed up to appear in New Line's family feature Mimzy.

The film revolves around two siblings, who find themselves gifted with strange talents after discovering a box of toys sent from the future. As the children's teachers and parents begin to notice the change in behaviour, they are all drawn into a strange and unique world.

Richardson will play the mother, whilst Wilson takes the role of a science teacher, says The Hollywood Reporter.
