Eddie Murphy improvised one of the funniest lines in 'Beverly Hills Cop: Axel F' in a scene with his real-life daughter

• One of Eddie Murphy's funniest lines in "Beverly Hills Cop: Axel F" was improvised.
• In the scene, Murphy's daughter Bria plays a police officer who arrests him.
• Director Mark Molloy told Business Insider that Murphy's improv skills enhanced the movie's humor.

Netflix's "Beverly Hills Cop: Axel F" is filled with laughs, but there's one joke in particular that was a family affair.

At the end of an action sequence in which Murphy's character Axel Foley is being chased while driving a police meter maid cart, Foley crashes on Rodeo Drive and is quickly apprehended by two female police officers. While being cuffed, Foley tells the officer it's "very embarrassing" what's happening. The officer, played by Murphy's eldest daughter Bria, responds, "You should have thought about that before your little joy ride."

But what Foley is embarrassed about is being thrown into their unusually small squad car. "Ya'll are the LEGO cops," Foley says.

It's a line that director Mark Molloy told Business Insider was completely improvised by Murphy.

"That's all Eddie," Molloy said.

Molloy, who is making his feature directing debut with "Axel F," said that Murphy improvised several times, but it was often nothing more than little one-liners.

"He likes to get it on the page first," Molloy said. "We have to have something on the page first that really works, and then Eddie is going to take it from there."

Molloy said other improvisations from Murphy happened during the helicopter scene with costar Joseph Gordon Levitt and between Murphy and a valet played by comic Affion Crockett.

But how did Muphy's daughter end up playing one of the police officers?

"Eddie mentioned that his daughter would love to be involved," Molloy said. "And there was talk that it was going to be for another role, but I told him, 'If she's going to be involved, I have the perfect role for her.' I think she should arrest you!' So he gets arrested by his daughter."

Bria, 34, is Murphy's eldest daughter from his marriage with ex-wife Nicole Mitchell. Bria has previously starred in movies "The Perfect Match" (2016) and "Amateur Night" (2016).

"Beverly Hills Cop: Axel F" is now streaming on Netflix.
