Jerry Ferrara wasn't the only cast member to respond to Mark Wahlberg's claims that "greedy" people were holding up the feature adaptation of "Entourage." On Friday, star Adrian Grenier used his Instagram account to comment on the film's development process. The status of the "Entourage" movie has been the source of much contention since the New York Post's Page Six column reported in September that Grenier and Ferrara were among the cast members who had not signed on for the planned film.

Grenier has long been excited about "Entourage." During an interview in April with HuffPost Live to discuss the documentary "How To Make Money Selling Drugs," he sounded hopeful that the film would come together. "Making movies is hard. It's going to take some time," he said, before addressing the fans: "I know you're anxious. I am too."

UPDATE: Speaking to TMZ on Sunday, "Entourage" star Kevin Connolly said the film was going to happen, and while nothing was official just yet, it looked likely to star production in January. Connolly had similar enthusiasm for the film back in April of this year. "Everything is such hard work, but that'll be like a vacation," Connolly said to HuffPost Entertainment about returning to "Entourage." "It can't happen fast enough for me."
