Richard Curtis To Write Doctor Who Episode

The BBC has the news that Richard Curtis of Blackadder fame (well that and all those films and stuff) is going to write a Doctor Who episode:

"These days the things you can watch together as a family are much fewer," he explained of his decision to step on board the Tardis, "so when you get something like Doctor Who or the X Factor, it is such a pleasure to sit down as a family".

And maybe he has a SF film in the works:

Curtis also revealed he was fascinated by time travel and was currently working on a low budget film about the subject.
