Actor Glen Powell solidifies his leading-man status by radiating reams of charisma and talent in the new movie “Hit Man.” Making good on his star-marking turns in “Top Gun: Maverick” and last year’s “Anyone But You,” the actor alternately plays brainy, hunky, awkward, confident, reckless, non-threatening, sharp, and average in the film. In the process, he subverts the stereotype of the “hit man” character and even comments on acting and fame itself. That he also co-wrote the screenplay with his director, Richard Linklater, only proves that Mr. Powell is the real deal.
