Billy Elliot.

Billy Elliot Directed by Stephen Daldry Starring Jamie Bell, Julie Walters, Gary Lewis and Jamie Draven *** (out of five) Rated R for language

THERE'S something inspiring about how people respond to life's challenges and it's particularly moving if the person who responds is a child. Billy Elliot and Pay it Forward tell the stories of two young men who overcome obstacles, respond to challenges and inspire their adult friends.

How does a boy who loves to dance survive in a mining town in northern England? That's the question Billy Elliot (Jamie Bell) has to face. When Mrs. Wilkinson's (Julie Walters) ballet class moves in to share the gym with Billy's boxing class, he sees the girls dance, drops his gloves, and joins in. This is not good news for his father (Gary Lewis) or his older brother (Jamie Draven). They're coal miners, on strike, and in their minds, a boy dancer is clearly a "poof."

But not Billy: he's attracted to his friend Debbie (Nicola Blackwell), and the cross-dressing antics of his friend Michael (Stuart Wells) don't much interest him. Billy loves to dance: his determination to move with grace and power find a happy resolution when he auditions for a national ballet school. In response to an examiner's question about how he feels when he dances, Billy says that it's like electricity runs through him. When first-time director Stephen Daldry captures Billy's dance, you feel the electricity, the energy that has the power to transform even the hearts of a tough father, and a disapproving brother. This is a very entertaining film, with a first-rate performance by Jamie Bell as Billy.

One good turn deserves another: that's the idea behind Pay it Forward. Kevin Spacey plays Eugene Simonet, a seventh-grade teacher and a challenged person because of a serious burn injury, who teaches social studies in an elementary school in Las Vegas.

His initial assignment for his students is to think of an idea that could change the world and put it into action. Trevor (Haley Joel Osment, the gifted young actor from The Sixth Sense) responds to this challenge. He postulates that if he did a really big favour for someone, and asked the person who received the favour not to "pay it back" but "pay it forward" by doing a big favour for three other people, eventually the world would be changed.

It's like an altruistic pyramid scheme -- Mother Teresa meets Amway: you do a favour, someone pays it forward three times--do the math: it works! Problem is, Las Vegas is a tough town and Trevor's mom Arlene (Helen Hunt) is a recovering alcoholic. One of Trevor's initial attempts to get his scheme underway is to fix up his mother and his teacher. Trevor suffers disappointment upon disappointment: the idea doesn't seem to work, but, goodness triumphs in the end, and his persistence and creativity inspire more people than he ever imagined.

Director Mimi Leder gets a little lost with her material, mixing subplots and flashbacks with the main story line, and choosing a too sweet, too sad way to bring it all to an end. The performances are all very fine, though, especially that of Kevin Spacey who, yet again, shows how more can be communicated through a gesture, or an expression than through several pages of script. And, as much as I was disappointed by the film's shortcomings, I was intrigued by the idea.

Trevor and Billy--two boys raised by single parents and inspired by teachers, show the resilience of the human spirit. "A little child shall lead them," says the prophet Isaiah. These two films go a long way towards inspiring viewers to respond to life's challenges with honesty, creativity and determination.
