Photo Flash: First Look - Bradley Cooper Returns to CBS's LIMITLESS Tonight!

Bradley Cooper (Broadway's THE ELEPHANT MAN) reprises his role as Senator Edward Morra on tonight's episode of LIMITLESS on CBS. Get a first look below!

In tonight's episode titled "A Dog's Breakfast", Brian's double life unravels when Senator Morra (Cooper) makes contact just as Brian's placed under 24-hour surveillance by the FBI following his rogue trip to Russia. Also, Mike and Ike tell an already suspicious Rebecca about Brian's off-book interaction with Morra's henchman, Sands.

The episode airs Tuesday, March 22 (10:00-11:00 PM, ET/PT) on the CBS Television Network. Jake McDorman also guest stars as Brian Finch.

LIMITLESS, based on the feature film, is a fast-paced drama about Brian Finch, who discovers the brain-boosting power of the mysterious drug NZT and is coerced by the FBI into using his extraordinary cognitive abilities to solve complex cases for them. Working closely with Brian in the major case squad in New York City is Agent Rebecca Harris, a formidable investigator with a dark past, and Agent Boyle, a former military officer and Rebecca's confidante. They report to Special Agent in Charge Nasreen "Naz" Pouran, a canny manipulator of the reins of power. Unbeknownst to the FBI, Brian also has a clandestine relationship with Senator Edward Morra (Academy Award nominee Bradley Cooper, recurring), a presidential hopeful and regular user of NZT who has plans of his own for his new protégé. Fueled now with a steady supply of NZT that enables him to use 100% of his brain capacity, Brian is more effective than all of the FBI agents combined, making him a criminal's worst nightmare and the greatest asset the Bureau has ever possessed.
