Have you seen the movie, "The greatest Showman" ? I have heard it is really good and has a lot of show tunes in it!
No, I haven't seen The Greatest Showman but I heard from a co-worker how much she loved it. She saw it 4 times
I think it definitely has a cult-like following. A lot of people I know saw it multiple times in theater also! 
Do you think it's an age thing with the Greatest Showman?
no, I think people of all ages love that movie!
Well, she's the only one I know as a fan and she is 18.  I know it is inspired by the story of P.T. Barnum's creation.
As in the circus performer? I have never actually seen the movie
Yes, Phineas Taylor Barnum, the American showman.
