Character actor in the body of a leading man, Billy Crudup (Almost Famous, Watchmen) is in negotiations to join the cast of Neighbourhood Watch, the Ben Stiller/Vince Vaughn led sci-fi comedy being directed by The Lonely Island's Akiva Schaffer.

If you're wondering who The Lonely Island are, they're the very funny comedy group behind such songs as "D**k in a Box" and "Motherlover." They work predominately with Saturday Night Live cast members, and all (including most famous member Andy Samberg). They're also the guys behind the hilarious, and criminally little seen comedy, Hot Rod - which Schaffer directed.

This is a big comedy, with huge stars, so hopefully Schaffer's sense of humour isn’t diluted too much and Stiller and Vaughn can get back to the ridiculously funny guys we know they are.
