Last February, there were reports that Haley Joel Osment will be appearing in the "Entourage" movie. However, not much details were dished out about the character of the former child star. Deadline just revealed that he will be joining the original cast composed of Jeremy Piven, Adrian Grenier, Jerry Ferrara, and Kevin Dillon. The website also reported that Billy Bob Thornton will have a role in the film adaptation of the popular HBO series.

For those who aren't familiar with Haley Joel Osment, he is the cute boy that starred in the suspense film "The Sixth Sense". His most famous line is "I can see dead people." He also appeared in the Hollywood blockbuster "Forrest Gump", "Pay It Forward", and "A.I. Artificial Intelligence".

Osment's latest movie is the horror dramedy "Tusk", which premiered at the Toronto International Film Festival. The film is scheduled for release on Sep. 19 and after that he will be promoting the "Entourage" movie where he has a supporting role.

During an interview with Den of Geek, the 26-year old actor revealed his role in the film. Some celebrities who make a cameo in the popular TV series appear as themselves, but Haley Joel Osment revealed that he will not play himself in the "Entourage" movie.

He said, "I'm a sort of a villainous character. Billy Bob Thornton plays my dad and we're sort of making trouble for Ari as he's trying to get on in his career and with Vince's career." The actor explained, "So a lot of it was just me, Jeremy and Billy Bob which was just work that I didn't want to end. A lot of fun."

In a separate interview with Grantland, the former child wonder revealed the plot of the film. Osment said, "It's a whole plotline where Billy Bob Thornton and I are two outsiders to the Entourage world and we basically give Ari a lot of trouble: We're like the money for something..."

He also shared his experience working with the original cast. The Los Angeles-born actor said, "Going on that set really was like a bunch of old friends from high school. Doug Ellin is such a cool presence - there's a real straightforward East Coast-ness to it. Those guys are East Coast guys and it was a really fun environment to be around, people who have fun with their jobs."
