"We start shooting in January, and now we can get to work. All the other stuff is in the past and now we have one goal, to make a great movie for the fans," Ferrara told the Associated Press Tuesday night on the red carpet for his new movie, "Last Vegas."
He equated the chemistry in the buddy movie starring Michael Douglas, Morgan Freeman, Robert De Niro, and Kevin Kline with his former series.
"Having worked on a show where chemistry between four guys was crucial, these guys made it instantly ... you bought it from moment one that these guys knew each other," Ferrara said of the "Last Vegas" cast.
"Entourage" creator Doug Ellin confirmed the movie's production on Monday evening when he tweeted a photo of himself and the cast arm-in-arm.
Since the film was announced early last year, various rumors surfaced about the why the movie had not gone into production, including cast members holding out for more money.
"There was a moment early on where it was a little frustrating, but then after a while, it was just kind of bewildering. Like, wow, I can't believe it's being talked about like this and none of it is even really true. It just got blown out of proportion," Ferrara said.
But the 33-year old actor stopped short of saying the rumors were fabricated.
"There weren't lies being told," he said. "In the same breath, it was amplified."
He added: "We always knew the movie was a go and the deal was gonna be done."
"Entourage" is a light portrait of Hollywood and young stardom that ran for eight seasons on HBO before ending in 2011.
Ferrara, who plays the character, "Turtle" in the show, is joined in the Warner Brothers big screen version by Jeremy Piven, Adrian Grenier, Kevin Dillon and Kevin Connolly.
