The Greatest Showman: Hugh Jackman on what working with Zac Efron was REALLY like (WATCH)

The actor, who formerly had huge success playing Wolverine in X-Men movies, stars alongside Efron in the hit musical; which lands on DVD and Blu-ray next week.

Jackman said in the above featurette: “It was so exciting to work with Zac.

“He’s been in many musicals but he hadn’t done it for at least ten years, and he was really excited and determined to do something he hadn’t done before.”

Efron himself added: “I just had a feeling.

“There was something about this project that felt special.”

Director Michael Gracey heaped praise on their genuine bond, saying: “It was really wonderful watching friendship build and watching the effect it had on the number [The Other Side].

“The song by the end becomes a celebration as they head into the circus, and you see Phillip’s mind blown by what he’s agreed to.”

The song ends with Efron’s character clapping eyes on Anne Wheeler (Zendaya) for the first time.

“Falling in love… that’s an incredible arc to have over the course of one song,” Gracey added.

The Greatest Showman was an enormous box office success, making over $430 million worldwide at the box office despite a slow start just before Christmas – and despite a lukewarm reception from critics.

It’s also been a music phenomenon, with the soundtrack album enjoying 14 non-consecutive weeks at the top of the UK charts.

This Is Me won the Golden Globe for Best Original Song, and has also had huge success on singles charts around the world.

Its other stars include Michelle Williams, Rebecca Ferguson, Keala Settle, Paul Sparks and Yahya Abdul-Mateen II.

The Greatest Showman is available on Blu-ray and DVD on May 14.
