David Tennant's demise as Doctor Who's 10th Time Lord feels like it's been coming forever.

Before he ends his run in the Tardis this Christmas, the actor returns to lend his voice to this epic animated adventure - but this is no simple Saturday morning kids' cartoon.

In all his time traveling adventures and alien escapades, it seems inconceivable that the Doctor has never made it to Area 51, also known as Dreamland - the supposed home of all things supernatural in the United States.

In this one-off special set in Roswell 1957, he does just that and - surprise, surprise - encounters aliens on the mysterious military base. Lots of 'em.

Having discovered a mysterious alien artifact in a dingy Roswell diner, the Doctor and new buddies Cassie (Georgia Moffett, who fans will remember from the episode The Doctor's Daughter) and Jimmy (David Warner) end up embroiled in a good old-fashioned Doctor Who romp.

Cue much running from ruthless aliens the Viperox and their sinister human pawn Colonel Stark (Peter Guinness) as the good Doctor does his best to figure a way to stop their alien army from destroying planet Earth.

The story, meanwhile, is every bit as engaging as previous Who episodes and unfolds at a satisfyingly speedy pace proving that animation can be equally as effective as live action.
