18-storey portrait of Nicole Kidman unveiled in Sydney to promote TV series The Undoing

She is one of Australia’s most famous faces and now an Olympic swimming pool sized portrait of Nicole Kidman has been unveiled in Sydney to promote her new TV series.

Australia’s biggest face in Hollywood has taken stardom to new heights by becoming the biggest face on the Sydney skyline.

An 18-storey portrait of A-list actress Nicole Kidman has been painted on the side of a Darlinghurst apartment building which was unveiled at the weekend.

The enormous mural - which is equivalent to the size of an Olympic swimming pool - was commissioned by streaming service Binge* to celebrate the new hit series The Undoing, in which Kidman - one of Australia’s most decorated actors - starred and co-produced.

A blown-away Kidman posted from the site this morning.

Sydney-siders saw the painting for the first time on Saturday, which took about two weeks to complete under a shroud of mystery.
