“WOW!” she wrote on Instagram. “Thank you Sydney for celebrating #TheUndoing.”

Streaming service Binge commissioned the larger-than-life piece of Kidman, 53, as her character in miniseries The Undoing to celebrate the program’s success.

The psychological thriller miniseries, which stars Kidman as therapist Grace Fraser, is the most-watched show on the streaming service since Binge launched in May, with its premiere episode luring in the biggest daily audience yet.

Eleven artists have spent more than 400 hours across two weeks bringing the 36-metre artwork to life at the Top of the Town apartment complex, on the corner of Craigend St and Victoria St.

The portrait, which is roughly the size of an Olympic swimming pool, will become the largest mural in the Southern Hemisphere when it is unveiled at 10am on Saturday.

Punters can view the artwork for three days before the portrait transitions into a second image before being taken down on November 23.
