People.com Lifestyle Style Diane Keaton Spotted Wearing Sexy, Thigh-High Snakeskin Boots on Set of New Film The icon is set to star opposite Elizabeth Lail in Mack & Rita, a film about a young woman who gets struck by lightening and wakes up as a 65-year-old By Hanna Flanagan Hanna Flanagan Style + Beauty Assistant, PEOPLE People Editorial Guidelines Published on April 1, 2021 12:59 PM Share Tweet Pin Email Photo: BACKGRID Diane Keaton was just spotted filming her upcoming comedy — and if her costume is any indication of her character, we have a lot to look forward to. On Wednesday, the actress, 75, was photographed in Palm Springs shooting scenes for the Katie Aselton-directed movie Mack & Rita wearing a white button-down shirt dress, thigh-high snakeskin boots and what appeared to be a long gray wig. Keaton's provocative ensemble is a stark departure from the Boho-chic wide-leg trousers, menswear-inspired jackets and brimmed hats we're used to seeing her in (the Oscar winner and fashion icon looked incredibly stylish, nonetheless). Over the past year, Keaton has shared a peek inside her eccentric wardrobe with her fans on Instagram, becoming a surprise #OOTD inspiration too many of her followers. Her hypebeast status even landed her a role in Gucci's latest campaign "Beloved Lines," which she stars in alongside Harry Styles, Awkwafina, Dakota Johnson, James Corden, Serena Williams and Sienna Miller. The campaign, which will debut on April 22, was shot by Spring Breakers filmmaker Harmony Korine. Father of the Bride Cast Reunites for a Brand New Wedding with Special Guests The Something's Gotta Give actress is set to play Aunt Rita in her upcoming film Mack & Rita, which also stars Elizabeth Lail as Mackenzie 'Mack.' According to IMBD, the comedy follows a "woman in her 30s who gets struck by lightning and wakes up as a 65-year-old." The movie also stars Dustin Milligan, Wendie Malick and Taylour Paige. The release date has not yet been announced. Mack & Rita comes on the heels of Keaton's film Love, Weddings & Other Disasters, in which she and Jeremy Irons play a pair matched on a blind date who find themselves falling unexpectedly in love. Irons' plays a fussy celebrity caterer, while Keaton's character is visually impaired. Tiffany Rose/Getty Director Dennis Dugan (Happy Gilmore) told PEOPLE last year that the film was made as a love letter to his wife, Sharon, after she asked him to write "a wedding movie because those films make her heart happy." Diane Keaton Wowed by The First Wives Club Impersonation Video: 'He Did a Better Job Than Me!' "I'm a total romantic," he said. "And I adore my wife. So I wrote one. About how everyone who works on or participates in a wedding aims for that perfect day – the perfect couple, perfect setting, flowers, everything. Meanwhile, all of their relationships are complete chaos. And then it took 14 years to get the film made." Despite the film taking more than a decade to reach audiences, Dugan said he "cried" and "laughed" as he wrote it. "I wrote the lyrics to all the songs because I wanted all of them to be integrally part of the story. I wanted them to be our songs, by our characters," he shared. Dugan previously acted alongside Keaton on the 1976 film Harry and Walter Go to New York. He says casting her was a no-brainer as they'd "remained friends forever."
