Doctor Who: The Curse of Fatal Death

A 1999 Doctor Who parody, produced by The BBC for Red Nose Day.

The Ninth Doctor (Rowan Atkinson) fights the Master (Jonathan Pryce) on an abandoned alien planet. He's engaged to his companion Emma (Julia Sawalha). When the Doctor is captured by Daleks, he's killed a few times over and rapidly cycles through being Richard E. Grant, Jim Broadbent, Hugh Grant and finally Joanna Lumley, who decides she'd actually rather shag the Master than fight him.

It's notably written by Steven Moffat, a full decade before he became in charge of Doctor Who proper. The occasional reference to the parody pops up in his episodes nowadays.
