While promoting his new film Django Unchained, Quentin Tarantino refused to answer questions from a Channel 4 News reporter regarding screen violence, saying: "I'm shutting your butt down."

The journalist, Krishnan Guru-Murthy, asked the Pulp Fiction director if he believed there was a direct link between on-screen and real violence, to which Tarantino responded: "Don't ask me questions like that. I'm not biting. I refuse your question."

When pushed for further clarification he responded: "I'm not your slave and you're not my master. You can't make me dance to your tune. I'm not your monkey."

He added: "I'm here to sell my movie. This is a commercial for the movie, make no mistake. I don't want to talk about the implications of violence.

"The reason I don't want to talk about is I've said everything I want to say about it. If anyone cares what I have to say about it, they can Google me, and they can look for 20 years on what I have to say about it. I haven't changed my opinion one iota."

When the journalist continued to ask questions on the topic, Tarantino added: "I'm shutting your butt down.

"I have explained it. I'm just not giving it to you... I refuse to repeat myself because you want me to for your show and your ratings."

Django Unchained, which has been nominated for a Best Picture Oscar, will be released on January 18.
