Diane Keaton is as kooky a style icon as ever filming Mack And Rita in Palm Springs

She has been an emblem of wacky fashion for decades.

And Diane Keaton was at it again when she got into costume for the shoot of the romantic comedy Mack And Rita in Palm Springs this week.

The 75-year-old made a splash in a pair of snakeskin print thigh-high stiletto boots with a massively oversized white dress shirt.

She wore a long straight hairdo reminiscent of her days starring in Woody Allen’s 1977 romantic comedy Annie Hall.

Diane, who first became a star opposite Al Pacino in The Godfather, could be seen expertly balancing on her sky-high heels crossing a parking lot.

While wearing the same ensemble the legendary screen queen shot a scene in which she drove a vintage Thunderbird across a dirt surface.

Her eye-popping outfits included another getup that featured baggy jeans, a comfortable-looking checked button-down shirt.

Diane was eating an ice cream cone while modeling one of the black bowler hats that have become her staple even in real life.

The movie stars Once Upon A Time actress Elizabeth Lail as Mackenzie ‘Mack’ and Diane as Aunt Rita – who are in fact the same person.

Through a bizarre set of circumstances Mack becomes transformed into a 70-year-old and decides to rechristen herself Rita, Deadline reports.

Taylour Paige who recently appeared in Ma Rainey’s Black Bottom is playing Mack’s young pal who will have to adjust to her friend aging up four decades.

Mack And Rita is being helmed by The League actress Katie Aselton who is making her feature film directorial debut with this project.
