Hugh Jackman says Greatest Showman 2 is being 'worked on'

Hugh Jackman has revealed that work has begun on a sequel to The Greatest Showman, but he doesn't know if he'll star in it.

The Wolverine star dished the info during an interview on BBC Radio 2 this week, saying a second film hasn't even been written and is only in the very early planning stages.

"There is talk of something going around but no one is really sure... I know they are, they're working on a treatment for something," said Jackman.

He added he'd like to be part of a potential sequel, but isn't sure if his character would be the main focus again.

The Greatest Showman also starred Keala Settle, Zac Efron, Michelle Williams and Zendaya in major roles.

Jackman also warned fans not to get too excited too soon.

"It did take eight years to get it made and that wasn't all eight years of convincing people. It takes a long time to write stuff."

Previously, the original film's director Michael Gracey kicked off sequel rumours while speaking to The Sun.

"When a movie becomes as big a success as this, it's only natural there is demand for a sequel. So those discussions have started and we are working on one right now," he said.

Jackman is bringing his Greatest Showman live show to Auckland's Spark Arena in September.
