Bradley Cooper is making his return to Limitless.

On Tuesday, Cooper reprises his role as Sen. Eddie Morra, whom viewers saw rise to power in the 2011 film and were reintroduced to in the Limitless premiere. PEOPLE has the the exclusive first look at the actor on set with star Jake McDorman (Brian Finch).

“Brian gets into a moral dilemma, where he’s being asked to do something he doesn’t want to do,” McDorman, 29, tells PEOPLE. “That goes against the wishes of Eddie Morra.”

In the show, Cooper’s character has supplied Brian with an antidote to the brain boosting drug NTZ, allowing him to take it without any nasty side effects. In return, he’s had to do some favors for Eddie.

“As Brian comes into direct opposition with Eddie’s agenda, you see them saying, ‘We can always not give you this,’ ” he says.

McDorman and Cooper became close on the set of American Sniper, where they shared a number of emotional scenes, including Cooper’s Chris Kyle visiting McDorman’s Ryan “Biggles” Job in the hospital.

“You always learn so much when you work with somebody of Bradley’s caliber,” says McDorman. “You can always relax as an actor when you know you’re doing a scene with somebody that’s more experienced or that you can trust is going to be on their game, because it makes you better.”

McDorman jokes he always seems to be in immense amounts of pain anytime he has a scene with Cooper – be it in American Sniper or the upcoming episode of Limitless.

“I’m like, ‘Dude, if I’m ever really in the hospital, you better be there. Somehow every time you show up, I’m wincing in pain,’ ” he jokes.

Cooper, who is an executive producer on Limitless, campaigned for McDorman to get the role, and the actor says he’ll always be appreciative of that.

“I was grateful to be in a movie with him once, let alone him lending his time to me on so many different occasions,’ says McDorman. “It’s the greatest gift he could ever have given me. I’ve learned so much.”

Limitless airs Tuesdays (10 p.m. ET) on CBS.
