For eight seasons the HBO series Entourage told the story of a fictional Hollywood A-lister and his band of friends — and now a movie is on the way. Deadline reports that a deal has been closed for a big-screen continuation of the series, that will see all of the original cast returning, including Adrian Grenier as star Vincent Chase and Jeremy Piven as the irascible Ari Gold. The Warner Bros. movie is budgeted at a relatively modest $30 million.
