(Cover) - EN Showbiz - Robert de Niro wants to turn his movie The Good Shepherd into a trilogy.

The 67-year-old star is best known for his role in The Godfather films, and is considered to be one of Hollywoods greatest actors and directors.

Robert received immense critical acclaim for the 2006 spy movie he directed, The Good Shepherd, and he has revealed he hopes to make a sequel, and possibly even a third movie follow-up.

The actor/director accepts he is nearing the end of his career, but insists he has the time and energy to make a few more movies at least.

"I have a few things I want to do, I only see myself doing at the most three more movies, he revealed at a press conference at the Toronto International Film Festival. "One of them would be a sequel to The Good Shepherd, maybe even a third part, I don't know."

The film told the tumultuous early history of Americas Central Intelligence Agency from the perspective of one mans life and starred Hollywood A-listers Matt Damon and Angelina Jolie.

Robert is currently promoting the movie Stone, which he stars in opposite Milla Jovovich and Edward Norton.

In the film Robert plays parole officer Jack Mabry who meets the wife of a convicted arsonist at a parole review. Edward stars as the arsonist and Milla plays the wife. (C) Cover Media
