Mr. Irons thinks that she may have been reacting to his straightforward approach to the reading. “I read what came to me off the page, without much intellectual study,” he says. Later, when getting ready to perform other poems by Eliot, he experimented with reading the lines with a lot of personality and acting, and then tried reading them with “nothing,” just straight off the page. He stuck with the latter. “I just try to become a voice,” he says.

Across his long film and television career, the 69-year-old actor is especially known for portraying historical or literary figures, such as Claus von Bülow in the 1990 film “Reversal of Fortune,” for which he won an Academy Award, Humbert Humbert in “Lolita” (1997), and Pope Alexander VI in the Showtime series “The Borgias” (2011-2013).

Before the reading in London years ago, Mr. Irons hadn’t read much of Eliot’s poetry. Now he has read all of Eliot’s major works, from “The Hollow Men” to “The Waste Land.” Next month, his audiobook recording “The Poems of T.S. Eliot” will be released, 75 years after the publication of Eliot’s “Four Quartets.”

That set of four poems, about the nature of time and the cycle of life, “is for me the apogee of his work,” Mr. Irons says. They reflect the struggle to get to “the still point of the turning world,” free from living in the past or the future. As Eliot writes, “The inner freedom from the practical desire, / The release from action and suffering, release from the inner / And the outer compulsion, yet surrounded / By a grace of sense…”

Mr. Irons says that he’s tried to get to his own still point by meditating occasionally, but he jokes that he more effectively gets there by smoking a cigarette on his own. “This isn’t getting as deep as I think Eliot is trying to get, but what I do is I smoke and I get out of noisy places and noisy dinners and I stand on the sidewalk or on the terrace,” he says. “I can’t bear the constant prattle of life.”

Mr. Irons, who grew up on the Isle of Wight in England, trained as an actor at the Bristol Old Vic Theatre School. One of his first major parts was in the 1981 television series “Brideshead Revisited,” based on the book by Evelyn Waugh. Since then he has acted in many other films and television shows inspired by books, such as the 2015 dystopian drama “High-Rise,” based on a J.G. Ballard novel. “I think it’s very rare that you get a film that’s better than a book, but you can find some that are almost as good,” Mr. Irons says.

When it comes to doing historical re-enactments, he thinks the characters and plot must reflect “the attitudes and understanding of life that they had at the time,” he says. He thought it was important that “The Borgias” reflected the nature of his character, Pope Alexander VI, who is notorious for his schemes to use the papacy to expand the power of his Borgia line, as well as for his many mistresses.

His new audiobook compiles readings of Eliot’s poetry that he originally did for BBC Radio. He thinks of poems and modern art the same way: Both are best understood emotionally rather than intellectually. “I know a lot of modern art goes over my head because I look at it and go, ‘It doesn’t mean anything to me.’ But sometimes you look at it and you’re just sort of gobsmacked.”

He applies a similar philosophy to acting as to reading poetry. He tries to be careful not to overact. He also aims to listen and react to the other actors in a scene. “I’ve always thought acting was more about listening than talking,” he says. He’s now starring in the London production of Eugene O’Neill’s “Long Day’s Journey into Night,” which will travel to the Brooklyn Academy of Music in May and then the Wallis Annenberg Center for the Performing Arts in Los Angeles in June.

In his down time, he and his wife, Sinéad Cusack, spend time at their castle in Ireland. Built in the 15th century and recently restored, it looks like it could be the setting for one of his period pieces. “I like walking, and I think Ireland suits my nature best of all and Los Angeles least of all,” he says. He spends as little time in L.A. as possible. “My instinct is not to live over the shop,” he says.

If he could pick a different era to live in, which would it be? “I think 1900 to 1912 was an extraordinary time,” he says, “and I think between the wars was a mad time and also quite fun to be around.” But he says that he’s satisfied enough with the present. “I’m happy to be healthy and alive when I am.”
