David Duchovny and Gillian Anderson return for the anticipated X-Files reboot, and ET was on the set getting the scoop on which one star gets stuck with most of the heavy lifting.

"Gillian has got a lot of it. She has got a lot of medical stuff and scientific stuff," Duchovny told ET. "They gave you the lion share of that crap."

"You have the lion share of being tortured every episode," Anderson pointed out.

"I do," Duchovny admitted. "I just faint apparently, and lose my gun all the time."

Loyal fans of the series have waited a long time for The X-Files comeback. At its peak, the revered sci-fi drama -- which ran for nine seasons from 1993 to 2002) the show pulled in 19 million viewers. But, Duchovny says it wasn't because of their detective prowess.
