'Who' movie to be confirmed at Comic-Con?

A Doctor Who movie starring David Tennant will be announced at the Comic-Con event later this month, according to reports.

Speculation is growing that the BBC will confirm the big screen version at the five-day convention, which is held in San Diego, California. Tennant will be attending alongside departing executive producer Russell T Davies.

Previously, Tennant has revealed that he has signed up for an unidentified "sci-fi project", while Davies has hinted that an announcement of a "special project" would be coming soon, telling Doctor Who Magazine: "News as and when, but I can promise, it's worth waiting for."

Tennant's Doctor will regenerate at the end of three Doctor Who specials, the last of which airs early next year. Matt Smith will then assume the lead role.

A spokesperson for BBC Films has previously confirmed that a script for a Who movie is "in development".
