The actresses team up for their new comedy, which hits theaters May 8
“Literally every person stares at [Sofia],” Witherspoon tells PEOPLE. “Men fall on the floor; women drop their purses. It’s like a commercial! Her hair is in slow motion.”
In the film, Witherspoon portrays an “inept” police officer who must protect Vergara, a drug dealer’s widow, from criminals and dirty cops.
“Her character is so sexy and suave, and I’m so dorky,” Witherspoon says.
The women struggled shooting some scenes together “because we were laughing so hard,” Witherspoon adds.
And her kids, Ava, 15, and Deacon, 11, had the same response: “It’s the ultimate compliment when your teenager likes it.”
