With his newfound bromance with Zac Efron showing no signs of fizzling out, Hugh Jackman can’t help but sing his co-star’s praises—quite literally.

As the pair’s musical drama The Greatest Showman, which follows the inception of show business with a creative aesthetic inspired by circus icon P.T. Barnum, heads towards its release date, the Wolverine actor fittingly took a melodic route while lauding the Disney alum on the red carpet aboard the Queen Mary 2 in New York City.

“I think Zac Efron is literally one of the most professional, hard-working, dedicated actors out there and he absolutely kills in this part," the 49-year-old belted out to E! News.

On a more serious note, Jackman revealed that he wasn't sure if his moment on the big screen with Efron would ever become a reality. "I really wasn't sure if this movie happened. No studio had ever greenlit in the last 23 years an original movie musical," he said. "It took four workshops, so many people involved and to be able to do it here on the biggest, grandest ship in the world, it's very showbiz. Barnum would have loved it."
