Starring: Ryan Reynolds, Jodie Comer, Joe Keery, Lil Rel Howery, Utkarsh Ambudkar, Taika Waititi Director: Shawn Levy

THE hero of “Free Guy” will discover that nothing about his world is real — which is fitting for a film that is itself a bit of an artificial construction, cribbing from influences like “The Truman Show” and “Groundhog Day” to craft a hollow facsimile of an action-comedy blockbuster about a background video game character who finally takes center stage. Ryan Reynolds is endearingly wholesome as this likeable digital nonentity, but once the story’s initial burst of cleverness fades, director Shawn Levy becomes bogged down in convoluted plotting and the overfamiliarity of his seize-the-day message.

The friendly, dull Guy (Reynolds) lives in Free City, a seemingly ordinary metropolis save for the fact that random acts of intense violence erupt all around him, which he smilingly accepts as just part of his day. What the audience quickly deduces is that he’s actually part of an open-world video game, called “Free City,” which allows players across the globe to roam around via avatars.

But Guy is an NPC, or non-player character — essentially, the unremarkable individuals in the background of video game scenes who have no personality. However, that changes after he meets the beautiful Molotov Girl (“Killing Eve”’s Jodie Comer) and decides to break out of his routine to talk to her — not knowing that he’s in a video game or that Molotov Girl is being controlled by Millie (also Comer), a shy game developer seeking proof that ruthless mogul Antwan (Taika Waititi) stole her code to create “Free City.”

Initially, it’s fun to witness Guy’s surreal surroundings. Levy wrings a few laughs from the notion that Guy doesn’t understand that how strange it is that army tanks would suddenly barrel down city streets or avatars fire rocket launchers at will. (Lil Rel Howery is amusing as Guy’s equally happy-go-lucky NPC best friend.) Satirizing the ubiquity of hyper-violent video games, “Free Guy” extracts comedy out of imagining what it would be like to inhabit such an extreme realm.

Unfortunately, the picture doesn’t offer much creative spark beyond that opening salvo, and quickly it becomes clear that writers Matt Lieberman and Zak Penn are merely transplanting the themes and tropes of previous films into this new setting. Like Jim Carrey’s Truman Burbank, Guy is meant to be an inoffensive everyman who has never dreamed big. And as with “Groundhog Day” (or “Edge of Tomorrow”), the film features a character who goes back to the beginning when he “dies” — in this case, waking up in bed in the morning — and has to start all over again, holding onto the knowledge he has already accumulated about his situation.

Reynolds and Comer have an adorable chemistry — interestingly enough, Molotov Girl is a far more assertive version of Millie than the one she shows the world — but the film only superficially examines the intriguing existential questions at the heart of her story. Instead, Levy unwisely focuses on a complicated narrative involving Millie and her friend Keys (Joe Keery) trying to prove that Antwan ripped off their designs to become rich with “Free City” as Antwan maniacally prepares for the launch of “Free City 2,” which could have serious repercussions for Guy. This subplot becomes increasingly more important, but it’s never compelling — especially once viewers realize it’s only there to provoke life-and-death stakes for the finale.

Ethan Tobman’s sleek production design imagines “Free City” in ways both stylish and cunningly banal, a smart riff on the fictional cities in video games that are merely the backdrop for explosions and murder. But Levy, whose pictures often tend toward the broad and sentimental, doesn’t have much feel for high-octane action sequences or nuanced comedy, and as a result “Free Guy” too often plays like a loose collection of random gags and concepts.

The movie is now being screened in Shenzhen.
