Leonardo DiCaprio Dropping Out of Mel Gibson's Viking Epic?

Leonardo DiCaprio has had major second thoughts about starring in Mel Gibson's Norse-language viking movie in the wake of the shamed director's legal battles with Oksana Grigorieva.

When asked if the Inception star was still planning to star in Mel's next historical movie, a source told Radar Online: “Not a chance.”

The decision is another professional setback for the Oscar-winning actor and director, who has also been dropped by his agents.

Detectives are investigating Oksana's claims that Mel, 54, punched her in the face twice as she held their infant daughter, Lucia, during a domestic dispute at his Malibu mansion on Jan. 6.

Mel’s profanity-laden phone calls, recorded by Oksana and obtained by Radar Online, are laced with racial slurs and demands for repeated sexual favors.

The viking film was to be Leo’s first picture with Mel but a source close to the 35-year-old says he doesn't want to risk his reputation by being associated with Mel.

“Leo has earned the right to pick and choose who he works with and Mel Gibson is not one of them,” the source told the Web site, which is seeking a comment from Leo himself on the issue.
