Robbie ColtraneRobbie ColtraneAfter a ten year break Robbie Coltrane is returning to the small screen to reprise his role in Cracker.

Fifty five-year-old Robbie has agreed to film a one-off special of the show which made him famous.

27/04Since leaving Cracker a decade ago, Robbie has been kept busy by Hollywood - particularly as gentle giant Hagrid in the Harry Potter films.

But he's finally found time to pick up his role of psychologist Fitz in the ITV drama which at the height of its popularity was pulling in 15 million viewers.

The new episode begins filming in the summer and ITV are hoping the one-off will give them the edge in Christmas ratings.
