Quentin Tarantino might have found an actor to relpace Kevin Costner in his latest film project, "Django Unchained". While a few weeks ago it was reported that Costner exited the project due to scheduling problem, it is now said that "Poseidon" actor Kurt Russell has been chosen to fill the role.

According to The Hollywood Reporter, Russell is in negotiation to play antagonist character Ace Woody. The character is described as a sadistic trainer of male fighting slaves and of female prostitutes. The site additionally reported that "Kill Bill" actress Laura Cayouette has been attached to play a widowed sister of Leonardo DiCaprio's Calvin Candie.

Meanwhile, bad news comes from the pre-production of the film project. One of the lead cast members, Christoph Waltz, has been injured when he joined a horse training session.

"Christoph Waltz was injured while training with his horse in preparation for his role," a rep for the Oscar-winning actor said in a statement. "Waltz is currently being treated for a dislocated pelvic bone and is looking forward to getting back in the saddle."

However, the accident will not affect the production schedule, which is slated to begin this November in New Orleans. As a result of the incident, Waltz would not be able to attend the premiere of Roman Polanski's "Carnage" at the New York Film Festival next Friday night, October 7.

Set in 1800s, "Django Unchained" follows a freed slave who, under the tutelage of a German bounty hunter Ace Woody, becomes a bad-ass bounty hunter himself. After assisting Ace in taking down some bad guys for profit, he tracks down his slave wife and liberates her from an evil plantation owner.

Jamie Foxx will play the titular character, while Samuel L. Jackson, Dennis Christopher and Gerald McRaney take other roles. The drama is set to open in U.S. theaters on Christmas day next year.
