from the art house to the megaplex

The thing that separates "Juno" from so many other films about teen pregnancy is that, in this case, the 16-year-old who finds herself in that predicament refuses to become a victim of her circumstances. From the moment she confirms the unwelcome news, Juno studies her options - abortion, raising the child as a single teen parent,adoption-then takes matters into her own hands.Like the Roman goddess who is her namesake, Juno is a bright, often sharp-tongued individual who prides herself on her observant cynicism and her way with a sarcastic quip. However, she's not above appealing to the adults in her life when the problems of the world get to be too much for her (though, in some cases, the grownups are coping with more serious issues than she is). Yet, Juno makes certain that it is she and she alone who will have the final say when it comes to determining the course of her own future and that of her child.

"Juno" is that rare low-budget, independent feature that finds unexpected success in the mainstream by striking a chord of recognition in audiences across the demographic spectrum. First-time screenwriter Diablo Cody hits pay dirt with a clear-eyed, largely unsentimental script that is not afraid to go off in unexpected and interesting directions and that avoids patronizing its Middle American characters.Juno's father and stepmother manage to take the news in stride, while the yuppie couple Juno alights on to be the child's adoptive parents are given a depth and complexity far beyond what a lesser writer might have afforded them. Director Jason Reitman keeps the quirkiness to a minimum and allows the scenes to play out in a naturalistic, unhurried way. Confident in the strength and appeal of his material, he lets the gentle human comedy speak for itself.

In a star-making turn, young Ellen Page takes a daring approach to her character, often bringing Juno right to the brink of un-likability, then pulling back at just the crucial moment, making us see how utterly likable she truly is. As the child's father, Michael Cera is virtually the same lovably passive nerd we found so endearing in "Superbad," while J.K. Simmons and especially Allison Janney give rich shadings to Juno's supportive parents. Jason Bateman and Jennifer Garner also make their mark as the couple who post their picture in the "baby wanted" section of the local throwaway.

"Juno" faces the downside of any independent film that unexpectedly finds itself ripped from the confines of the art houses and suddenly duking it out at the multiplexes with all those high-budget, high-octane, testosterone-laden blockbusters - namely the risk of over-inflated expectations. Thus, my advice is to look beyond all the hype and box office records and simply let "Juno" sneak up on and take a hold of you in its own quiet, inimitable fashion. I think it works best that way.

I saw this film at the 2007 Toronto International Film Festival.Juno MacGuff (played magnificently by TIFF regular Ellen Page), finds herself pregnant, knocked up by her best friend Paulie Bleeker (Michael Cera) on their first attempt at sex. Juno, with the help of her best friend Leah (Olivia Thirlby), takes it upon herself to find some adoptive parents. Courtesy of the local Penny Saver, she soon finds childless couple Mark and Vanessa (Jason Bateman and Jennifer Garner).

With the help of her surprisingly supportive father (J.K. Simmons) and stepmom (Allison Janney), Juno embarks on her pregnancy, which ends up affecting everyone in some unexpected and touching ways.This was a great film, probably the best I've seen so far at the festival. Ellen Page gives a wonderful performance as Juno, convincingly portraying her as a real independent free spirit. Michael Cera was good and funny, although I occasionally had trouble divorcing his character from George-Michael Bluth.

J.K. Simmons and Allison Janney did a nice turn as Juno's parents. Jennifer Garner and Jason Bateman were great as the adoptive parents who, while seemingly the perfect suburban couple on the outside, have their own sets of issues on the inside. Bateman especially gave a great performance as Mark, who is worried about sacrificing his own dreams as he connects with Juno over a shared love of music and the reality of the baby sinks in.

This is director Jason Reitman's follow up to his first feature film, Thank You For Smoking, which also debuted at the festival on the exact same date and time in 2005. This is screenwriter Diablo Cody's first feature film, and she put together a refreshing take on the typical teen pregnancy story with some great dialogue for the actors. The audience laughed so hard at some of the lines, they drowned out the ones that followed.
