English star Benedict Cumberbatch has been roped in for the adaptation of `Dungeons & Dragons`. The 44-year-old joins the cast of the upcoming big screen project that includes Chris Pine, Michelle Rodriguez, and Rege-Jean Page, reports aceshowbiz.com. "After narrating the animated film, Benedict couldn`t not be in the film version. Filming has been in the UK too, so it was convenient for him travel-wise," a source told The Sun newspaper.

This is not the first time Cumberbatch is featuring in a fantasy adaptation. He previously has voiced Smaug and Sauron in Peter Jackson`s "The Hobbit" trilogy.
