Amid the buzz surrounding the casting for True Detective's season two, the HBO drama recently made some unorthodox hires: porn stars.

Sources say at least two major talents in the adult film industry, Amia Miley and Peta Jensen, both 24, were hired for a deliriously vast, Eyes Wide Shut-caliber orgy sequence involving dozens of naked bodies. According to participants in the scene, the sequence was shot over the past few days in a Pasadena mansion. Season two stars Colin Farrell and Rachel McAdams were also present for filming.

Funny twist: The adult actresses apparently are among the few people who actually don't get totally naked.

HBO declined to comment on the hires, and all participants have signed nondisclosure agreements that prevent them from discussing their work on the secretive series created by Nic Pizzolatto, but a source says the production didn't hire Miley and Jensen for their porn experience. The women signed up with the extras casting service the show is using and were employed along with dozens of other men and women willing to strip down for the Emmy-winning drama.

Miley, who was recently named the 44th "hottest" porn star by Complex, also appeared in the gritty Power Rangers remake that surfaced on the Internet in February. It's unclear whether additional adult film actors — male or female — were involved in the orgy shoot.
