'Doctor Who' movie on the way?

Producers are planning to bring back Billie Piper for a Doctor Who movie, according to a report.The decision was prompted by the realisation that the show's budget was constraining it in terms of sets and effects, according to the Daily Star.A source told the paper that the proposed movie would also see assistant Rose Tyler, played by Piper, reunited with David Tennant."There’s been so much interest in Doctor Who since the show was sold to America that a film is the natural progression," said the source."Top of our list is to get Billie on board – not only was she amazingly popular, it would be really exciting to get her back with the Doc."
