Executive producer Mark Wahlberg recently revealed the film version of the hit Tv series had stalled because some stars were being "greedy", demanding too much money to reprise their popular characters.
His comments came shortly after reports suggested Grenier and co-star Jerry Ferrara were the ones who had yet to sign contracts, and on Friday (18Oct13), The Devil Wears Prada actor took to his Instagram.com blog to shed some light on the claims.
In the note, Grenier, who played lead star, actor Vincent Chase, claimed he was not motivated by money and instead had been standing up for his co-stars to prevent producers from allegedly taking advantage of them.
He wrote, "To all Entourage fans. I owe it to you to make a couple things clear. I take my role as Vince on the show & off very seriously. All decisions I make personally and for business are for the principle of friendship and brotherhood. It has, & never will be about the money for me.
"I will always stand up for the boys... & do what I can to make sure they are treated fairly, and not be taken advantage of by anybody. The spirit of Entourage is about sharing the opportunities given to us and I will sign any deal that gives All the boys an opportunity to share in the upside of success EQUAllY. I assure you, despite the perception, there is no greed in my heart."
However, Grenier insists the film will get made, adding: "Remember, it will all work out in the end. It always does."
Fellow Entourage star Kevin Connolly has since assured fans that the project will go ahead, revealing on Sunday (20Oct13) that the movie is expected to start shooting in January (14).
Jeremy Piven and Kevin Dillon made up the rest of the main Entourage cast, which wrapped its final season on America's HBO network in 2011.
