For this week’s cover story, “Catch-22” co-stars George Clooney and Christopher Abbott sat down with Variety to discuss their upcoming Hulu miniseries and overall body of work.

Abbott admitted he has never seen “ER,” which Clooney starred in. Clooney, on the other hand, said he watched Abbott’s HBO series “Girls” “religiously.”

Abbott said “Solaris” is the first Clooney movie he ever saw. Abbott joked that the film was in the porn section in his hometown video store, where he used to work. Clooney responded, “It went right to porn. Not even straight to DVD. Or VHS. Straight to porn.”

The conversation then turned to their favorite Batman actors. Abbott apparently liked Clooney as Batman in 1997’s “Batman & Robin.” Clooney thought otherwise: “I screwed it up so badly I’m not allowed to weigh in on any of those subject matters anymore.”

“Catch-22” premieres May 17 on Hulu. Clooney and Abbott star alongside Hugh Laurie and Kyle Chandler. Clooney is also a director and executive producer for the series.
