Though its Hollywood is fleshed out with a big, delightful cast, Wonder Man is built on the skeleton of a classic two-hander. Yahya Abdul-Mateen II, whose resume in this genre includes the Aquaman movies as well as HBO’s subversive Watchmen series, is our self-sabotaging would-be hero, Simon Williams, a struggling actor first seen getting fired from American Horror Story for overthinking a minor role. A cinephile obsessively devoted to his craft, he’s the kind of guy who makes notes about which books his single-scene character would be reading and expects everyone on set to care about it as much as he does. This same self-centeredness compels his girlfriend (Olivia Thirlby) to move out of their modest apartment without warning.
