Juno (2007)

Juno (Ellen Page) is a whip-smart teen confronting an unplanned pregnancy by her classmate Bleeker (Michael Cera). With the help of her hot best friend Leah (Olivia Thirlby), Juno finds her unborn child a 'perfect' set of parents: an affluent suburban couple, Mark and Vanessa (Jason Bateman and Jennifer Garner), longing to adopt. Luckily, Juno has the total support of her parents (J.K. Simmons and Allison Janney) as she faces some tough decisions, flirts with adulthood and ultimately figures out where she belongs.
