He was on the This Morning sofa on Wednesday and told presenters Phillip Schofield and Holly Willoughby it was an amazing experience.
Davis took part in the ITV series, which sees famous faces put their own perspectives on issues close to their heart, to tell the story of a family of dwarves in 1940s Germany.
"It's about a family who were a group of dwarf entertainers. There were seven of them in the family and they used to work in central and Eastern Europe performing," he explained.
"As Jews they were captured and deported to Auschwitz in 1944.
"There story is one of inspiration but also survival as well."
The actor said he found it difficult filming some of the scenes for the documentary, especially seeing first hand the conditions they were subjected to.
The family had a 'the show must go on' mentality.

"I had stories of people I had interviewed, survivors and historians, so I went in there with all of this information and it was really moving," he said.
He added: "It was difficult when I went to the wooded area were people waited to go into the gas chambers - standing there was quite emotional.
The successful actor has a career which spans more than 30 years, featuring in blockbusters such as Star Wars, Willow and Harry Potter.
He will also be returning in a one of special of his smash hit series Life's Too Short.
The mockumentary, which was created and written by Ricky Gervais and Stephen Merchant, sees Davis playing a fictionalised version of himself.
But Warwick is assured his character is now a much 'kinder and nicer' than the previous series.
Perspectives is shown on UTV on Sundays at 10pm.
