Gillian Anderson is back at work investigating things on TV! This time, she's got a British accent, blonde hair and better fitting clothing (sorry, "X-Files") and she's teaming up with "The Good Wife's" Archie Panjabi for "The Fall."

"The Fall" is the "X-Files," "The Good Wife" and "Once Upon a Time" crossover you dreamed about ... sort of. Anderson stars as Stella Gibson in "The Fall," a BBC2 drama about a serial killer and the investigator brought in to take him down, which also stars Panjabi and "Once Upon a Time's" Jamie Dornan.

Allan Cubitt wrote the series.

"'The Fall' is a unique, forensic and characterful take on a classic genre that continues BBC Two's commitment to original British drama in 2012," Ben Stephenson, controller of BBC Drama Commissioning, said in a statement. "Cubitt’s rich and complex psychological thriller combined with another compelling performance from Gillian Anderson will keep viewers on the edge of their seats."
