In the "Entourage" series finale, everyone lived happily ever after, with Vince (Adrian Grenier) jetting off to get married to writer Sophia (Alice Eve), Sloan (Emmanuelle Chriqui) getting back together with E (Kevin Connolly) and Ari (Jeremy Piven) quitting his job to save his marriage, only to be offered the gig of chairman and CEO of Time Warner.
According to Ellin, “There are interesting developments about Ari as a studio head, and that’s still the first page for me. But foremost is the friendship between the guys who are still hanging out and going to fun parties, and it continues with the same characters." He's still under an overall deal at HBO and has developed two projects with the network, one with Ed Burns and the other with Spike Lee, that didn't get picked up.
Finke notes that HBO has made no firm committment to go into production with the film yet, and that they haven't yet seen the completed script. Focusing on the guys hanging out and going to parties sounds... pretty much exactly what the show's been like for the eight years of its low-stakes TV run, so no one's likely to accuse this one of coming from a wild new direction and shaking things up beyond recognition.
