None of the people who made this movie contacted David Irving. He is the one who initiated the legal action not Deborah Lipstadt. Biased much ? -

The trailer for Denial shows a deliberate misrepresentation of what David Irving said to Deborah Lipstadt in Atlanta Georgia on November 11 1994. The trailer shows Irving saying "I've got a thousand dollars to give anyone who can show me a document that proves the holocaust". In real life Lipstadt claimed she knew "a blueprint of a gas chamber complete with the openings through which the SS tipped the pellets of cyanide". Irving's response was "I have here a thousand dollars for you if you can produce to this audience, now or at any time in the future, this document about which you have just lied to them".
