Speaking to the Radio Time podcast, Kidman, who measures at five feet and 11 inches, was told she was “too tall” to have a career in Hollywood.
“I say I’m 5-foot-10-1/2, but I’m really 5-foot-11,” Kidman said.
Kidman said she first faced rejection over height as a child when she turned up for an audition.
“I remember auditioning for Annie. It was a big call-out with hundreds of people. I didn’t have an agent, I just turned up. My mum was like: ‘Oh, please, do we have to? How long is this going to take?’, she said.
“I had to talk my way into the audition because they were measuring you. I was over the mark! You had to be under 5ft 2in, and I was 5ft 4in! I was like ‘Please?’”
Kidman said while she was eventually allowed to audition, she didn’t even get a call back from the audition.
The actress, who has 72 films and 22 TV show appearances to her name, said she was teased as a child for her height which often requests kitten heels when walking red carpet events.
“Whenever I go on the red carpet, I get sent shoes that are always so high. I’m like, ‘Do they have a kitten heel? I’m going to be the tallest person – a giraffe!’,” Kidman said.
