Friday night saw a brotherly lovefest at the world premiere of New Line’s Dwayne JohnsonKevin Hart action-comedyCentral Intelligence” at the Regency Village Theater in Westwood.

The red carpet festivities began with dueling fan buses — designated Team Hart and Team Johnson — in a continuation of the mock feud that started last year over who had the better fans.

Hart insisted on the black carpet that he loved hanging out with Johnson, adding: “I really made a good friend. We didn’t run to our trailers between takes like a lot of people do on sets.”

“It’s like having a brother,” Johnson said, “Even if I never work with him again, he’ll always be my brother.”

The screening featured an intro by director Rawson Marshall Thurber, who noted that his wife wasn’t in attendance because she gave birth 10 days earlier. He persuaded the crowd to yell “Hi, Sarah” in unison to his spouse.

Amy Ryan, who played a super-serious CIA agent on the trail of Johnson and Hart’s characters, isn’t quite as stealthy offscreen.

“I’d be a lousy CIA agent in real life. I’d probably get killed the first day,” she quipped.

The after party replicated the film’s Central High School setting, with cheerleaders, sports trophies, high school grub and a Centaur mascot.

Warner Bros. execs Kevin Tsujihara, Toby Emmerich and Sue Kroll also attended the premiere, the second in four days for the studio following Tuesday’s premiere of “The Conjuring 2.”

“Central Intelligence” opens June 17.
