Who knows if we will ever see a return of the HBO series Entourage, but one of its stars says that there's just one thing standing in the way of making it happen. Running for eight seasons between 2004 and 2011, the show had a continuation of sorts when it was given a feature film follow-up in 2015. The series follows a Hollywood A-lister along with a group of childhood friends he's made his entourage. It is inspired by the life of Mark Wahlberg, who served as an executive producer on the show alongside Stephen Levinson.
