Also on board are "Extras" star Stephen Merchant, who also co-created "The Office," and pro skateboarder Ryan Sheckler (MTV's "Life of Ryan").
The 20th Century Fox film centers on Derek Thompson (Johnson), a minor-league hockey player whose nickname is the Tooth Fairy because of his ability to knock out opposing players' teeth. Judd plays his girlfriend.
When he discourages a youngster, Derek is ordered to one week's hard labor as a real tooth fairy, complete with wings, magic wand and frilly tutu. Along the way, he rediscovers his forgotten dreams.
Andrews will play Lily, a high-ranking, acerbic supervisor with the Tooth Fairy Department charged with overseeing Derek's stint as a tooth fairy. The 72-year-old British screen icon was last seen in the 2004 "Princess Diaries" sequel.
Merchant plays Tracy, a socially awkward, low-level tooth fairy who has not yet earned his wings but is assigned to be Derek's case worker and trainer.
Sheckler plays arrogant young hockey player Mick Donnelly, who makes a pit stop in the minor leagues before heading to the NHL and treats Derek like a has-been.
Filming is set to begin in October in Vancouver with Michael Lembeck (the "Santa Clause" sequels) directing.
