This year's Venice Film Festival has attracted its usual array of glittering A-listers, all dressed to the nines for the lavish occasion.

However, there were several stars who unfortunately seemed to miss the fashion mark as they hit the red carpet, with overly daring or outlandish looks. 

Among the slew of sartorial blunders was Shailene Woodley, who ensured all eyes were on her at the premiere of George Clooney's new film Jay Kelly, but for all the wrong reasons.

The American actress, 33, who does not feature in the movie itself but was in attendance to support her close friend George, put on a very leggy display in a silky black minidress that looked more suitable for a night out rather than a red carpet. 

Adding further height to the outfit with a pair of open-toed black high heels, she struck several sultry poses while at the event.

She accessorised with a statement silver, green and black necklace and a pair of diamond earrings, which she put on full display with her hair in a half-up-do. 

Laura Dern also failed to impress with her bold look as she arrived on the red carpet in a quirky green dress with a black barbed wire-esque overlay.

Meanwhile, Naomi Watts suffered a style misstep in a beautiful nude mesh gown which featured elegant floral detailing but was largely ruined by an oddly-shaped black bow. 

The British actress, 56, looked more smitten than ever as she planted a kiss on her husband Billy Crudup's cheek at the star-studded Jay Kelly premiere.   

She cosied up to the American actor, 57, who stars as Timothy in the upcoming comedy-drama, on the red carpet. 

Naomi's dress featured a plunging sweetheart neckline and was adorned with sequinned floral embellishments.

Completed with a silk bow at the waist, the floaty mesh skirt gathered in a stunning train on the floor. 

She accessorised with diamond drop earrings and wore her blonde locks in soft waves as she posed up a storm for the cameras. 

And the couple couldn't keep their hands off each other, with Naomi showering her husband with kisses during their red carpet moment. 

Billy looked dapper in a cream tuxedo, paired with a crisp white shirt, black bow tie, and matching tailored trousers. 

He finished the look with black patent leather brogues as he lovingly escorted Naomi down the red carpet. 

Naomi and Billy began dating in 2017 after they met on set of the Netflix series Gypsy. After making their first red carpet debut in 2022 they went on to tie the knot in New York a year later. 

Meanwhile, other stars failing to impress at the Venice Film Festival included Emily Mortimer, who opted for a white lace midi dress teamed with eye-catching heels. 

Elsewhere, Alba Rohrwacher opted for a bold royal blue satin gown which she paired with platform black heels.

Italian actress Eva Robin also commanded attention in a bright yellow gown as she attended the Venice Film Festival on Thursday.

Alicia Silverstone's gown also featured in the worst dressed list, with the actress wearing a white frock with long sleeves and a high neckline. 

Jay Kelly, set for release on November 14, features an all-star cast including Adam Sandler, George Clooney, Emily Mortimer, Laura Dern, Billy, and Greta Gerwig. 

The film sees George take on the title role of the Hollywood movie star who 'always plays himself'.

The trailer sees George's character questioning his life choices, despite being fawned over by fans and staff.

On a trip to an Italian film festival in his honour, joined by his devoted manager Ron, played by Adam Sandler, he's hailed as the 'hero of cinema' before being brutally asked about always playing himself.

To which George's character snaps back: 'You know how difficult it is to be yourself? You try it.'

Jay Kelly is seen continuously reminding himself that he is 'Jay Kelly' as he and Ron embark on a trip through Europe amid the disappearing appeal of showbiz.

The official synopsis reads: 'Famous movie actor Jay Kelly and his devoted manager Ron embark on a whirlwind and unexpectedly profound journey through Europe. 

'Along the way, both men are forced to confront the choices they’ve made, the relationships with their loved ones, and the legacies they’ll leave behind.'
