The chemistry between Rockwell and Kendrick drives the movie. They’re fast and wonderful together. But Mr. Right has an abundance of strong supporting performances as well.

This sort of violent comedy — think “True Lies’’ meets “Grosse Pointe Blank’’ — is tough to pull off, but Spanish director Paco Cabezas and screenwriter Max Landis (“American Ultra’’) nail a screwball fantasy vibe that stops just inches short of downright silliness.

A crowd-pleaser despite its missteps and occasionally because of them, the pic enlivens some stale conceits about killers-for-hire and the women who love them.

It has a bouncy sense of lunacy, wearing its derivative junkiness on its sleeve with surprising lightness of authority.

Rockwell and Kendrick, both of whom can really sell this film’s brand of laid-back quirk, keep things lively.
