Dwayne "The Rock" Johnson by Eric Charbonneau/WireImage.com
What has happened to Dwayne "The Rock" Johnson? The former pro wrestler and star of the über-macho The Scorpion King has lately been attracted to lighter material like Disney's The Game Plan and this summer's Get Smart.

It's safe to expect more of the same, as he's just signed on for 20th Century Fox's The Tooth Fairy. The role finds Johnson as an ordinary man who's brought in (à la Santa Clause) to save the tooth-fairy kingdom. Not surprisingly, Michael Lembeck, who wrote the second and third installments of Clause, is slated to direct, with shooting expected to begin this summer. - Adam Bryant
