The Arrowverse isn't the only TV universe headed for a crisis.

In a new trailer for Doctor Who Season 12, the Doctor herself issues a warning about the "big, serious crisis" to come. She doesn't offer any further details before the promo throws her into action with car chases, explosions and deadly new aliens. The trailer also offers a look at Stephen Fry and Sir Lenny Henry CBE in their Whoverse debuts.
