Director Sean Penn was not fazed by the media's negative response to his new film 'The Last Face' after the film's screening. Penn said in a news conference on Friday, "I just finished the film, so it?s not a discussion that I think I can be of any value to, I stand behind the film as it is and certainly everyone is going to be well entitled to their response.? 'The Last Face' which tells the love story of two aid workers during the Liberian War will have its official premiere on Friday.
