In Edward Berger’s Oscar-tipped drama, the three actors play cardinals vying to become pope. Ahead of the film’s UK release, they form a huddle to discuss fame, food – and why Trump won

Faith, death and vengeful vaping: of all the Oscar contenders this year, Conclave is the one that best combines chewy religious inquiry and lavish side-eye. Adapted by Wolf Hall screenwriter Peter Straughan from the Robert Harris novel, Conclave has been directed by All Quiet on the Western Front’s Edward Berger as a heavy-breathing battle for hearts, minds and power.

Ralph Fiennes stars as Cardinal Lawrence, who, after the sudden death of the pope, must park his own religious doubts to wrangle the 113 cardinals who have descended on the Vatican. These men will be sequestered until they can elect one of their number as the new pontiff. Among them are the gentle progressive Bellini (Stanley Tucci) and smooth traditionalist Tremblay (John Lithgow). Both have secrets. But are they as lethal as those of their friends – and rivals?
