In the years since Mel Gibson fell from the grace of his celebrity, we’ve been through the Mel Gibson-is-canceled stage (which happened but didn’t take), the Mel Gibson-gets-a-cameo-as-found-object-of-infamy stage, the Mel Gibson-crawls-back-to-nail-a-nutzoid-lead-role stage (remember “The Beaver”?), the Mel Gibson-has-become-the-hero-of-Z-thrillers-that-exploit-his-disreputability stage, the Mel Gibson-has-a-real-deal-comeback-with-“Hacksaw Ridge” stage, the Hollywood-still-won’t-accept-him-as-an-actor stage, and (at last) the Mel Gibson-barely-even-has-to-be-an-actor-because-he’s-now-a-meme stage.
