Collins interested in surprise 'Doctor Who' cameo
Movie icon Joan Collins has hinted she may be interested in a cameo role on legendary British sci-fi series 'Doctor Who' - after she fell for the charms of the show's star David Tennant.
The 'Dynasty' star visited the set after being hounded by her grandchildren to arrange a guided tour of the BBC show's set - and expected to be bored by the backstage activities.
