It might be cliche for me to compare “Last Looks” (2022) to “Get Shorty” or “Jackie Brown.” Or it might have been cliche for executive producer and star Charlie Hunnam to make a movie like those two from his childhood. Or it might have been cliche for Howard Michael Gould’s novel, upon which the film is based, to evoke Elmore Leonard. Regardless, it works as an above-average, inside-Hollywood whodunit, thanks to Hunnam’s low-key detective and a scenery-devouring display from thespian and murder suspect Mel Gibson (who’s still got it as an actor, despite having a screw loose in real life).
