David Tenant is planning to quit Dr. Who after the upcoming series, according to insiders.

The actor has signed a £1 million contract to make a third series of the show, but he will look to pursue a career in Hollywood thereafter.

The forthcoming season will be the show's fourth, after Christopher Ecclestone played the Doctor in the opening series.

A insider reportedly said: "David absolutely loves the programme but if it comes back for a fifth season bosses will have to find a new Doctor Who."
