Loserville charts the rise of a typical American high-school nerd from 1971 as he and his sci-fi-obsessed misfit friends try to change the world from their position of insignificance. It runs at the Garrick Theatre.
Guests at the party included Bourne, Davis, cast members Richard Lowe, Eliza Hope Bennett, Stewart Clarke, Charlotte Harwood, Lil' Chris, Robbie Boyle and Aaron Sidwell.
Other guests at the after-party, which was held at the National Gallery Cafe, included Olympic swimmer Rebecca Adlington, McFly members Dougie Poynter, Danny Jones and Harry Judd, tv presenter Emma Willis, and actors Colin Morgan, Bradley James and Danielle Hope.
