Juno is the quirky protagonist in the 2007 film 'Juno' written by Diablo Cody and directed by Jason Reitman. At the beginning of the film she narrates that it all began with a chair, referring to the night she slept with her best friend and bandmate, Paulie Bleeker. This one encounter leaves her 16, pregnant and completely unprepared to take care of a child. She explores her options and after ruling out an abortion decides to look for a loving couple to adopt her child to, stumbling upon Mark and Vanessa Loring in the PennySaver. With the love of her supportive parents and some help from friend Leah, Juno must not only cope with her pregnancy but must learn some very grown-up lessons.

Juno is not your typical teen, full of sarcasm and cynicism. But she also slowly shows, throughout the film, a vulnerable and innocent side more fitting her young years.

The character of Juno is played by Canadian actress Ellen Page. For this performance, Ellen Page has received several major award nominations including Best Actress nominations from the Golden Globes, Screen Actors Guild and Academy Awards.
