The director of Charlie and the Chocolate Factory has spent millions on training squirrels to crack nuts.

Tim Burton was reportedly determined to recreate the "nut Room" scene in Roald Dahl's novel for his film reports The Sun.

Tim said: "We used actual rodents. From birth, we sent them to training school for six months."

A source added: "Tim was determined to bring the nut room to life. Using squirrels proved too difficult in the first film, but he spent millions of pounds getting it right."

The film stars Johnny Depp as Willy Wonka.
