The mere idea of a Mexican road movie might make anyone a bit queasy, but director Alfonso Cuaron's rollicking film, Y Tu Mama Tambien, is well worth the ride. In fact, Cuaron is so at ease with his native landscape—a social mosaic that sweeps from the upper-crust parlors of Mexico City to the squalor of roadside shacks on its outskirts—that his film is propelled along effortlessly from start to finish. Y Tu Mama Tambien, or "And Your Mother Too," follows Tenoch and Julio, two overheated 17-year-olds on summer break in the capital, who manage to entice Tenoch's cousin's sexy but distraught wife, Luisa (played by Spanish actress Maribel Verdu), to join them on a quixotic trip to the coast. As glimpses of their sprawling country pass by the car windows, and their conversations turn from adolescent to earnest, the characters undergo their own separate journeys. The shifting dynamic among the three is practically combustible, and Gael Garcia Bernal, as Julio, delivers a performance as exhilarating as his turn in last year's Amores Perros. This is a delightful, provocative film from modern-day Mexico, and yet one more sign (along with films such as Amores Perros and Cronos) of another Mexican revolution under way. (Rating: ★★★1/2)
