On the heels of BAFTA, Golden Globe and Critics Choice award wins, Peter Straughan has now won the Oscar for best adapted screenplay for Conclave. This is Straughan’s second Oscar nomination and first win.

Focus Features' Conclave officially became an Oscar-winner Sunday with the honor of Best Adapted Screenplay for writer Peter Straughan, who turned the bestselling Robert Harris novel of the same name into an acclaimed shooting script.

"Conclave" walked away with only one Oscar win; still, the film's themes about embracing doubt amid uncertainty and using one's platform to speak against injustices will have staying power long after awards night.

British playwright Peter Straughan clinched the Oscar for Best Adapted Screenplay for 'Conclave,' a gripping papal thriller. The story follows Cardinal Lawrence, embroiled in a Vatican conspiracy. 'Conclave' features actors like Ralph Fiennes and John Lithgow,

“Conclave” won best picture at the BAFTAs in London last month as well as best British film. Straughan’s pre-Oscars awards haul was particularly significant, having won best adapted screenplay at the BAFTAs, Critics Choice Awards and Golden Globes.

As long predicted, writer Peter Straughan earned the Best Adapted Screenplay Oscar for the Focus Features release directed by Edward Berger, adapted from a Robert Harris novel.

Sean Baker has won the original screenplay Oscar for “Anora,” a comedy-drama about a sex worker who marries the son of a Russian oligarch.
