Behind the Scenes of Every the Rock and Kevin Hart Film: Viral Set Clashes and Genuine Friendship
By Sarah Jenkins
Their on-screen chemistry is so recognizable that directors now use it as shorthand for instant energy. In 2019, Johnson arranged for Hart to make a surprise uncredited appearance in Fast & Furious Presents: Hobbs & Shaw as Air Marshal Dinkley, an over-eager federal agent desperate to join Hobbs' team. Hart wrote most of his dialogue on the day of filming, riffing across a four-minute scene that provided a welcome break from the film's relentless vehicle stunts.
In 2022, Warner Bros. leveraged their vocal chemistry for DC League of Super-Pets, casting Johnson as Superman's faithful canine Krypto and Hart as Ace, an aloof shelter hound. Even though voice acting limits physical comedy, the production recorded Johnson and Hart in the same sound booth whenever possible, a rarity in studio animation, to preserve their rapid-fire conversational rhythm.
