The drama of ITV's Quiz has proved too much for some viewers, who found the scenes more tense than watching a real-life Who Wants to Be a Millionaire? show.
The TV production of the west end play that detailed the infamous moment that Charles Ingram cheated his way to £1m by going all the way on the Chris Tarrant hosted quiz in 2001.
It was later found that he was being helped by his wife, in a coughing scandal that was unearthed by eagle-eared producers and his money was rescinded in one of the most dramatic moments in TV history.
With Michael Sheen taking the role of Tarrant and James Macfadyen is Ingram in the three-part series that has become one of the biggest hits of the coronavirus lockdown.
As the action unfurled, viewers at home got so engrossed that some forgot that the Millionaire show was not for real and was a drama.

One tweeted: "Finding myself looking for the question and answers to pop up each time, wanting to play along."

Another wrote: "Why am I on the edge of my seat like I don't know the outcome?! Great tv"
A third summed it up perfectly, tweeting: "Why am I so on the edge of my seat as to whether he gets the answer right when I know the whole show is based on the fact they cheated and won the million pounds."
