No actress on television works harder than *Orphan Black'*s Tatiana Maslany. As the show's central clone, she plays more than 10 different characters—often playing multiple clones in a given scene. She finally got recognized for her work with an Emmy nomination this year (we'll find out if she wins on Sunday), but she's not the only person responsible for her flawless clone performances. Maslany gets a lot of help from Canadian VFX studio Intelligent Creatures, which combines multiples takes of the actress playing different clones and stitches them together into one scene. This installment of Design FX goes into the studio's process for making Season 4's climactic fight between two of Maslany's clones: Sarah Manning and Rachel Duncan. Check it out above.
