British actor Augustus Prew (Kick-Ass 2) has been cast as the lead in Mamma Dallas, HBO’s comedy pilot by Enlightened creator Mike White. Written, directed and executive produced by White, the half-hour project follows a conservative family in Texas who unwittingly hire a hard-living drag queen, Liberty (Prew), as their live-in nanny. Liberty appears to be an attractive woman with a flirty side — but she’s really a drag queen with an upbeat personality. On a path that leads to jail or prostitution or both, Liberty (also known as Albert) sees a future that will destroy his basically optimistic spirit and re-invents himself to get a job as a nanny to three children of a conservative, Texan family. With its setup, the project evokes a bit of the Robin Williams classic Mrs. Doubtfire. White is executive producing with Dede Gardner.

Prew’s recent credits include the UK feature High-Rise and Discovery Channel’s gold-rush-era miniseries Klondike. He is repped by ICM Partners, UK’s Curtis Brown and Schachter/Brown.
