Set in New York in 1982, This is Our Youth follows 48 hours in the lives of three young souls. Cera plays Warren, a 19-year-old who has just stolen $15,000 from his abuse father. Warren's buddy Dennis (Kieran Culkin) is a drug dealer who puts the stolen cash to good use while Jessica (Tavi Gevinson) is the love interest, who Warren years for.

"Michael Cera, making his New York stage debut, once again perfectly captures being an awkward man-boy, while veteran fashionista and acting newbie Tavi Gevinson matches his goofy nervous energy," said Mark Kennedy of the Associated Press, "Kieran Culkin is marvelous as their smug, narcissistic friend. Spending two hours watching these wealthy, unmoored slackers is a treat, even without the contact high."

"These post-adolescent slackers living on Manhattan's Upper West Side in 1982 could easily have grown up to reproduce themselves as our current crop of privileged youth. In fact, this demographic is turning out in strong numbers for the show, drawn by its cast of baby stars Michael Cera, Kieran Culkin and Tavi Gevinson," wrote Marilyn Stasio of Variety.

"Cera...Playing not too far from his familiar dorky screen persona, he makes an impressive stage debut, fully mining the pathos and humor of the fumbling Warren and easily scoring the evening's biggest laughs," said Frank Scheck of the Hollywood Reporter.

"Michael Cera, he of the turtle face and pipe-cleaner arms, has cornered the market on screen nerdism to the point you would think there was nothing left for him to mine from the indignations of the socially awkward. Turns out, given material deep enough, there is," said Jesse Green of Vulture.

This is Our Youth runs through till Sunday, January 4, 2015 at the Cort Theatre (138 West 48 Street).
