This movie is based on a true story. Denial is based on the case against Historian Deborah Lipstadt. Lipstadt was the subject of a high profile suit brought about by Holocaust denier David Irving. Irving had written a few books based around his ideas about the Holocaust, as had Lipstadt. To say they didn't see eye to eye would be an understatement.
It amazes me that anyone could deny the Holocaust. But, there are a lot of things in life that amaze me. I personally have met a survivor of Josef Mengele's twin experiments. I do not understand how anyone could hear their story and think it is not fact. I understand that people continue to idolize Hitler, but to also deny the existence of the gas chambers infuriates me.
Deborah Libstadt turned her case over to a few lawyers as the lawsuit was brought in Britain. It was extremely hard for Deborah to do this as she is used to doing her own research and speaking for herself. Her lawyers manage to win her case.
The film focuses only on the case, but watch for the scenes where Deborah and her lawyers tour Auschwitz. If those scenes don't tear you up, then you must be heartless. This is an interesting look into a not talked about part of history.
