Shooting on Warner Bros.’ movie version of the HBO series “Entourage” has started in Los Angeles.

The film includes the show’s original cast of Kevin Connolly, Adrian Grenier, Kevin Dillon, Jerry Ferrara and Jeremy Piven. Billy Bob Thornton and Haley Joel Osment also star as a father and son while returning cast members also include Perrey Reeves, Emmanuelle Chriqui and Rhys Coiro.

“Entourage” creator Doug Ellin is directing from his own screenplay. He posted a shot of the cast on his Twitter account over the weekend.

Mark Wahlberg, Stephen Levinson and Ellin are producing, with Wayne Carmona exec producing.

The show ended its eight-season run in September 2011. The series finale, watched by 2.6 million viewers, concluded with a cliffhanger to set up the movie.

Piven’s Ari Gold character, who had been a talent agency chief in the series, is portraying a studio chief in the movie.

The movie was chosen by lottery in June as one of 31 productions eligible to receive California’s Film and Television Tax Credit, landing seventh on the list with $5.81 million — the highest allocation among the 14 features selected. The commission lists the film as generating $29.1 million in production expenditures in California with 35 production days, 41 cast members, 265 crew members and 2,204 extras.

The film will also shoot in Miami.
