Meet the Real-Life Figures at the Heart of AMC’s Quiz

AMC’s three-part limited series Quiz tells the strange and fascinating true story of Major Charles Ingram, a British army veteran who was accused in 2001 of cheating his way to the top prize in the U.K. edition of Who Wants to Be a Millionaire?

Because the show was the jewel in ITV network’s crown, the ensuing scandal became headline news and involved some very prominent execs from the U.K. TV industry. Ahead of Quiz‘s premiere, here’s a guide to the real-life figures at the center of the furor, and the actors who portray them.

Matthew Macfadyen as Major Charles Ingram

Succession‘s Matthew Macfadyen leads the cast as Charles Ingram, an affable former Army major whose deeply odd route to the show’s top prize aroused suspicions even as he was playing the game. At one point, he correctly picked Craig David as the answer to a question, despite admitting a few moments earlier that he’d never heard of the British R&B singer. To this day, Ingram maintains his innocence.

Sian Clifford as Diana Ingram

Fleabag actress Sian Clifford co-stars as Diana Ingram, Charles’s stoic wife, who watches from the studio audience as her husband wins the seven-figure prize. Diana had already competed on the show herself, and had connections to a network of Millionaire super-fans who had worked out how to game the selection process. Diana was accused of deception alongside her husband.

Michael Jibson as Tecwen Whittock


Michael Jibson (1917, Star Wars: The Last Jedi) plays Tecwen Whittock, a college lecturer from Cardiff, Wales, who’s implicated alongside the Ingrams. When production staff watched the episodes back, they noticed that a prominent cough could often be heard when Ingram read out the correct answer to a question he was weighing. This cough was attributed to Whittock, but the Welshman insisted he was innocent and had suffered from a persistent cough for years.

Michael Sheen as Chris Tarrant


After playing real-life figures including former P.M. Tony Blair and Richard Nixon interviewer David Frost, Michael Sheen gives another transformative performance as British TV legend Chris Tarrant. (Sheen’s spot-on turn inspired us to look at nine other actors who memorably transformed to play real people.) As Who Want to Be a Millionaire?‘s host, he found himself summoned to testify when the Ingrams were accused of cheating. Pictures of him arriving at Southwark Crown Court were splashed all over the tabloids the next day.

Risteárd Cooper as David Liddiment

Acclaimed Irish stage actor Risteárd Cooper plays David Liddiment, who served as the BBC’s head of entertainment before becoming ITV’s Director of Programs and Channels in 1997. The Who Wants to Be a Millionaire? “coughing scandal” happened on his watch, so he definitely had a vested interest in bringing the alleged cheats to justice.

Aisling Bea as Claudia Rosencrantz

Irish actress-comedian Aisling Bea (State of the Union, The Fall) portrays well respected British television exec Claudia Rosencrantz, who as ITV’s Controller of Entertainment commissioned a string of hits including Who Wants to Be a Millionaire?, Simon Cowell’s The X Factor and Britain’s Got Talent, Gordon Ramsay vehicle Hell’s Kitchen, and reality smash Love Island.

Mark Bonnar as Paul Smith


Doctor Who and Line of Duty alum Mark Bonnar appears as Paul Smith CBE, founder of Celador, the production company which made Who Wants to Be a Millionaire for ITV. In Quiz, we see him calling the police after he reviews footage of Ingram’s million-pound journey and becomes convinced he didn’t play fair and square.
