Paramount Pictures Sandra Bullock—once crowned by the media as “America’s Sweetheart”—plays Loretta Sage, the author of a string of frothy imaginative adventures set in steamy, dreamy exotic locales. At the onset of a book tour to promote what she intends to be the final installment of her Lost City franchise, she’s kidnapped by an obscenely rich superfan (Daniel Radcliffe) who thinks Loretta’s literary world-building has roots in a real place, and a real treasure. He whisks Loretta off on his private jet and demands that she lead him to the legendary Lost City of D. But, thanks to the pings from Loretta’s Apple watch, help is on the way. Alan Caprison (Channing Tatum), who poses as the himbo cover character for Loretta’s top-selling books, heads off to rescue her, alongside a former Navy SEAL (Brad Pitt) now in the extraction business. The setup puts Loretta and Alan together on a volcanic tropical island—and into an over-the-top, thrill-filled romp that feels like one of Loretta’s rollicking romances springing to life. Directors Aaron and Adam Nee—brothers whose previous collaborations were smaller, more modest films, including Band of Robbers and The Last Romantic—up their game considerably here. The Lost City has all the hallmarks of a star-studded, blowout, blockbuster-style caper with chases, explosions, escapes, scuffles and merry, B-movie self-awareness. Its movie DNA is girded with sturdy strands of Romancing the Stone, Raiders of the Lost Ark and even a bit of Bond, especially in the hyper-inflated villainy of Radcliffe’s character and his obsession with something so delectably beyond the reach of his riches. But the movie belongs to its two lead stars as it crackles throughout on their crisp chemistry. Bullock leans into her natural prowess for action-comedy combo platters that she previously displayed in The Heat, The Proposal, Miss Congeniality and Oceans 8. Channing plays off his sculpted, eye-candy physicality—as demonstrated in Logan Lucky, Magic Mike, 21 Jump Street and Hail, Caesar!—to find the soft soulfulness of his character as genuine romantic sparks begin to fly between Loretta and Alan. Many times, the movie is laugh-out-loud funny, thanks to a jauntily clever script by Seth Gordon, who certainly knows how to cut to the funny bone; he directed Horrible Bosses and Identity Thief and episodes of TV’s Modern Family, Parks and Recreation and The Office. Packed with wily running gags and brisk, quippy one-liners that sometimes feel spontaneous and ad-libbed, it’s a fun-filled frolic with a hilariously saucy, playfully risqué spin—like when Loretta has a sudden, unexpectedly close encounter with Alan’s nether regions, characters riff on what the “D” in the Lost City might really stand for, or an island legend is given a carnal cap-off. The supporting cast also gets space to show their stuff. Pitt, especially, is a total scene-stealer, channeling the cool, confident alpha-male badassery he displayed in Once Upon a Time in Hollywood. “How are you so handsome?” Loretta asks him, smitten by his bravado and dashing good looks. “My father was a weatherman,” he replies. The Office star Oscar Nuñez, who appeared alongside Bullock in The Proposal, makes the most of his moments as a helpful, island-loving air-cargo pilot. Da’Vine Joy, who held her own alongside comedy super-titan Eddie Murphy in Dolemiteis My Name, brings sass and style to the role of Loretta’s hard-working assistant, Beth. Stay until the credits are completely over to see a coda that offers Pitt a surprise reappearance. And speaking of reappearances, will this zesty zip of ripping rom-commery have a sequel? We can only hope for an encore, especially since Bullock recently announced she’s ready to take a break from the movies. Maybe Loretta is thinking of retiring her franchise and her characters, but it sure feels like there’s certainly enough gas in TheLost City tank for a crowd-pleasing followup. “Let’s see what’s on the other side of that door,” Alan’s Fabio-like cover character, Dash McMahon, says in an opening fantasy sequence. Here’s hoping it opens to something that reunites these two immensely likeable lovebirds. Next, The 100 Best Movies of All Time
