Demi Moore dazzles alongside co-stars Diane Lane, Calista Flockhart, and Naomi Watts as they lead stars at Feud: Capote Vs. The Swans premiere in New York

Demi Moore was among a number of dazzling stars who gathered at the premiere of FX’s new series, Feud: Capote vs. The Swans, held at the Museum of Modern Art in New York on Tuesday.

The Indecent Proposal star, 61, channelled old Hollywood glam in a spectacular black and white gown in the shape on a swan — a nod to the show, set in the 1960’s and 70’s. The actress accessorized her show-stopping outfit with dangling earrings and silver bracelets. 

Many of her co-stars, including Diane Lane, 59, opted for grand monochrome looks, with Diane wowing in a busty black and white gown. 

Calista Flockhart, 59, was a vision in a plunging dress with a black torso and a striped bottom. Meanwhile Naomi Watts, 55, sizzled in a black lace ensemble with side cut-outs.

The ‘Swans’ were the New York City socialites who welcomed author Truman Capote into their high-flying circles, only to ruthlessly jettison him when he aired out their dirty laundry in public.

Like Demi, Naomi added a swan element to her look, holding a unique silver swan clutch in her hand. The British actress teamed her look with elegant elbow length black satin gloves.

Her blonde tresses were parted on the side, and she further sparkled up her look with chunky silver earrings.

Watts was joined by her husband Billy Crudup, 55, who looked dashing in a black suit and a bowtie. 

Feud: Capote vs. The Swans stars Tom Hollander as Truman Capote, in the story of his dramatic exile from the New York beau monde.

Truman charmed his way into the highest echelons of New York society, becoming the confidante of many of its top trophy wives, whom he called his ‘Swans.’

The break came in 1975, when he published a now infamous short story in Esquire called La Côte Basque, 1965, dishing the dirt on his extremely thinly-veiled friends.

Furious and wounded at his betrayal, the Swans closed ranks and ejected him from their circle, much to Truman’s shock and dismay.

‘What did they expect?’ he moaned. ‘I’m a writer, and I use everything. Did all those people think I was there just to entertain them?’

Of all the Swans, Babe, pictured in 1967 was among those most hurt by the Esquire piece, inasmuch as she had regarded Truman as a close and trusted friend.

Watts features as Babe Paley (pictured in 1967), the wife of CBS president Bill Paley and a woman widely regarded as one of the most beautiful and stylish in New York 

Moore stars as Ann ‘Bang-Bang’ Woodward who died in 1975 at age 59. She was a showgirl, model, and radio actress turned notorious Manhattan socialite. 

She became a scandalous figure when she killed her wealthy husband at home with a shotgun and avoided having to go to trial by insisting she thought he was a burglar. 

When she got word that Truman’s story was about to air out her past all over again and suggest she murdered her husband deliberately, Ann committed suicide.

‘Well, that’s that,’ her mother-in-law remarked. ‘She shot my son, and Truman just murdered her, and so now I suppose we don’t have to worry about that anymore.’

Diane plays the acid-tongued society maven Nancy ‘Slim’ Keith, who husband-hopped from Howard Hawks to Leland Heyward to an English baron. 

In La Côte Basque, 1965, Slim is rendered as ‘Lady Ina Coolbirth,’ an American who has married her way into the British aristocracy and spends the story gleefully spilling her dearest friends’ nastiest secrets.
