Ben Stiller and Naomi Watts in While We're Young.

Ben Stiller re-teams with director Noah Baumbach (Greenberg) for While We’re Young, a very funny movie about artistic integrity and learning to grow up.

Stiller and Naomi Watts play a 40-something couple who are content, but perhaps a little bored. They meet a 20-something couple (Adam Driver and Amanda Seyfried) and find themselves drawn to them and aspects of their “really cool” lifestyle. As it turns out, the Stiller and Driver characters are both film documentarians. This leads to initial bonding—but then it leads to big problems.

This is Stiller’s funniest movie since Tropic Thunder, and Watts is every bit as funny (especially when she cuts loose in a hip-hop dance class). Driver and Seyfried are adorable, and a little scary, as the younger couple who still listen to vinyl and watch VHS tapes, because it’s cool and retro.

Beastie Boy Adam Horovitz and Maria Dizzia get laughs as Stiller’s older friends who just had a baby and are worried about the emotional welfare of their two pals.

Baumbach is always amusing, and this is one of his better films.

While We’re Young is now playing at the Camelot Theaters (2300 E. Baristo Road, Palm Springs; 760-325-6565) and the Century Theatres at The River (71800 Highway 111, Rancho Mirage; 760-836-1940).
