Most enthused perhaps for the series to finally reach theatres is its perennial guest star, Canadian Emmanuelle Chriqui, known for playing the character Sloan in the HBO hit.
In a recent interview, Chriqui said, "I think it's amazing. I think people are going to love it. It's the best version of the show."
Loosely based on the life of producer and actor Mark Wahlberg, Entourage lasted eight seasons before going off the air in 2011.
For those unfamiliar with the show, it told the story of Vincent Chase, played by Adrian Grenier, his brother and two closest friends from Queens, N.Y., who all move out to LA as Vincent becomes an A-list Hollywood star.
The film picks up shortly after the events of the finale, as Chase re-unites with his former agent, Ari Gold, played by Selfridges' Jeremy Piven, who's now a studio head and wants to re-team with his former client.
If you haven't yet seen the trailer, here's your chance.
