Sci-Fi This Week: Orphan Black Season Four Premieres Thursday

The cult hit Orphan Black is back! Tatiana Maslany returns in her multi-role turn in the fourth season of the show, which moves to Thursdays this season.

So far Sarah Manning (Maslany) has discovered that she is part of a long-term clone experiment; joined forces with her clone “sisters” from Project Leda; sought to undermine the ongoing efforts of the Dyad Institute and the Neolution movement; and squared off against a line of militarized male clones from Project Castor. In Season Four look for the introduction of a new clone — M.K. — and an ever-deepening mystery that brings Sarah around full circle to the clone who started it all: Beth Childs.

Get an early peek at the first four minutes from the episode below.

Also this week: Indigo (Laura Vandervoort) is back on Supergirl, teaming up with Non to use Kryptonian mind control on the citizens of National City. The Legends of Tomorrow meet DC’s Jonah Hex when they head to the Old West to hide out from assassins sent by the Time Masters, and on Once Upon A Time Ruby and Mulan meet none other than Dorothy in the land of Oz.

Though we won’t be including Hunters in our weekly coverage, the new alien conspiracy drama should be worth checking out when it debuts on Syfy Channel tonight.
