Ben Stiller re-teams with Greenburg (2010) writer-director Noah Baumbach to capture hilarious truth in the dynamic between two differently-aged New York couples. Stiller and Naomi Watts play mid-40's Manhattanites who befriend Amanda Seyfried and Adam Driver's 20-something Brooklyn Bohemians. In the generation that separates these pairs, cassettes and books have become kitsch enjoyed ironically by the young, while their elders get increasingly engrossed in digital technology.

Both duos are aspiring filmmakers, one more opportunistically than the other, and these varying ambitions move the story. There's also an interesting turn form Beastie Boy, Adam Horowitz as Stiller's buddy whose wife just had their first child. The whole ensemble, though shines on the strength of Baumbach's deftly funny writing, which conjures a number of familiar situations played out subversively. An Ayahuasca ceremony in an apartment and a final call-out at a black tie gala, equal parts wit and slapstick, are made great in their absurdity.

With a script where you miss great lines from laughing at the previous one, While We're Young is another gem of barely heightened reality from a director on a creative roll. Having found his comedic tone, and actors like Stiller and Greta Gerwig, star of his upcoming Mistress America (2015), to collaborate with, Baumbach has quietly become a leading voice in the genre. The hipsters and yuppies both get nailed in the year's funniest film so far.

Final Grade: A- | 91/100 | ★★★½
