Julian McMahon (Nip/Tuck) has joined the growing cast of Relativity Media's corporate thriller Paranoia.

The story centers on Adam Cassidy (Liam Hemsworth), an ambitious entry-level employee at a telecommunications firm, who gets into trouble with the company's CEO. Instead of turning him in, the executive sends him to spy on a rival company. Julian McMahon will play Meechum, although no further details were given regarding his character. Harrison Ford, Gary Oldman, Lucas Till, and Amber Heard also star.

Robert Luketic is directing from a screenplay by Jason Dean Hall, adapted from the Joseph Finder of the same name. Relativity Media is handling domestic distribution and co-financing with international distributor IM Global. Production is scheduled to begin next month.
