Attack of the clones?

The trailer for the second season of BBC America’s cult hit “Orphan Black” airs during the “Doctor Who” Christmas special on December 25 — and, for fans who don’t want to wait that long, online right now.

The spot, which features a voiceover of Tatiana Maslany in her myriad of accents as her characters’ faces fade in through DNA strands and test tubes of colored substances, suggests that the clones are growing to accept that they’re “part of a sisterhood like no other” but that they still insist they are each “one of a kind.”

Will they fight back against their makers this season? Fans will have to wait for the season two debut April 19 on BBC America.
