"Kind of weird when you're walking down a stairwell and you're tempted to knock on someone's door and say that's my song," Jackman said in a video he posted on social media. "Don't worry I'm not going to do it!"

He labeled the video "A million dreams..."

Whoever was listening to it must have really been into the song, because it is clearly audible from the hall Jackman is in while he appears to be heading out for a bike ride.

Jackman played P.T. Barnum in the 2017 hit that also starred Michelle Williams, Zac Efron and Rebecca Ferguson.

The film, the song "This Is Me" and Jackman were all nominated for Golden Globes. "This Is Me" won the Golden Globe for best original song - motion picture and also was nominated for a best original song Oscar.
