Tooth Fairy (2010, USA/CDN) C-101m. ** D: Michael Lembeck. Starring Dwayne Johnson, Ashley Judd, Stephen Merchant, Ryan Sheckler, Seth McFarlane, Julie Andrews, Billy Crystal. A movie that sounds like an idiotic idea: Dwayne 'The Rock' Johnson stars as a hard-hitting but unsuccessful ice hockey player, who destroys a little girl's belief in the Tooth Fairy and is then transformed into one himself. Some laughs, and some surprising star cameos, but otherwise this falls flat and remains far too formulaic.
