Hugh Jackman has unveiled the outrageous transformation he made for his latest film Song Sung Blue.

And fans of the 56–year–old Wolverine star may be in for a shock.

The handsome box-office favourite dropped a new trailer for the movie on his social media on Tuesday – and the famed song-and-dance man is barely recognisable.

For Hugh’s role in the film as a Neil Diamond impersonator, the Greatest Showman star adopted the hitmaker’s famed late ’70s look – including lavish sideburns and a shoulder-length bob cut.

Scenes previewed in the trailer include Hugh performing note–perfect versions of Diamond’s hits, including his 1969 chart-topper and karaoke favourite, Sweet Caroline.

Another trailer highlight sees the leading man dancing in his underwear, while another segment features Hugh in a teary scene with his co–star Kate Hudson.

Announcing that the film is set for a holiday season release, Hugh shared the preview on his Instagram and included a caption:

‘This is a love story. This is a film about second chances, family, hardship, great love and chasing your dreams.

‘This film is a Christmas gift (with popcorn).’

Based on Greg Koh’s 2008 documentary of the same name, Song Sung Blue follows down-on-his-luck Milwaukee musician, Mike Sardina (Hugh Jackman).

He teams with another struggling muso, Claire (played by Kate Hudson), to form a Neil Diamond tribute double-act they dub ‘Lightning & Thunder’.

But behind the scenes, the couple struggle with family and their personal demons – including trauma and alcohol abuse.

The film is a drama based on the real-life story of a married couple who won hometown fame after forming a band paying tribute to ’70s superstar Neil Diamond.

Claire was known for her impersonation of famed US country superstar Patsy Cline, while her husband Mike wowed fans with his take on hitmaker Diamond.

While never quite making it big outside of their hometown, the duo once played a support spot for famed rockers Pearl Jam.

The dramatic musical co-stars The Sopranos star Michael Imperioli, Jim Belushi and Succession’s Fisher Stevens.

The drama will be written and directed by Craig Brewer who is known for the 2011 remake of Footloose.

The title of both projects is a nod to Diamond’s single Song Sung Blue which topped the charts in 1972.

The new film will be a chance for Jackman to show off his famed skills as a song and dance man after his huge success in the Broadway stage musical The Music Man.

Meanwhile, Kate Hudson, 45, released her debut album Glorious in 2024.
