In this gripping courtroom drama, acclaimed historian Deborah Lipstadt, portrayed by Rachel Weisz, faces a monumental legal battle when she is sued for libel by Holocaust denier David Irving, played by Timothy Spall. The catch is that under British law, the burden of proof falls on Lipstadt and her legal team to prove that the Holocaust actually happened, a fact she believes should never need defending. Directed by Mick Jackson and written by David Hare, the film follows her high-stakes struggle alongside her barrister, played by Tom Wilkinson, as they devise a bold strategy to counter Irving's self-representation. Rather than putting survivors on the stand to relive their trauma, they must dismantle Irving's lies with historical evidence, turning the courtroom into a tense intellectual battlefield. With a stellar supporting cast including Andrew Scott, the film is a taut, thought-provoking drama that explores the dangerous power of lies and the immense courage required to confront them. It is a compelling portrait of the fight for historical truth against overwhelming odds.
