The first trailer for Doctor Who season 12 has been released by the BBC.

It looks like everyone’s favorite Time Lord is going to have a very busy twelfth season. The trailer for the next installment of the BBC’s mega-franchise is jam-packed with action, villains, and guest stars!

On top of the first appearance of series guest stars Stephen Fry, Goran Visnjic, and Lenny Henry, the trailer features the return of one of Doctor Who’s major villains. The Cybermen, who first appeared on the series in 1966, are back to fight once more. We’ll see if the Thirteenth Doctor will be successful in thwarting their plan to turn the world into a race of machines!
