Rigby and Boys, who won a Whatsonstage.com Award for Avenue Q, join the previously announced Paul Holowaty (Hollyoaks) and Gregg Lowe (New Boy).
In Wolfboy, two teenagers share an intimate adventure in a boy's home. Bernie has attempted suicide and David is a street hustler who may or may not have the powers of a wolf.
The musical comedy, based on a play by Brad Fraser, has music and lyrics by Leon Parris and is adapted and directed by Russell Labey, who had a hit at Trafalgar 2 last year with New Boy, which starred Nicholas Hoult and was nominated for two 2010 Whatsonstage.com Awards.
Oliver!, which broke box office records by taking over £15million in advance sales, is directed by Rupert Goold, based on Sam Mendes’ 1994 staging at the London Palladium. The new version is currently booking until 26 February 2011.
