It absolutely is that. As some have said anyone that has gone to a drama school will be trained in song and dance. Yes there are the odd Piers Brosnan or Russell Crowe but in the main people seem amazed when actors have to sing and dance and they are very good. I never got past a drama class when I was a teenager but we did all that stuff even at that level.
Not long back someone shared a video of a merry Benedict Cumberbatch, known for playing rather posh uptight characters, dancing brilliantly in a club with some friends and being amazed, my first thought was to the contrary that he’s probably gone through 200 hours of dance classes.
Now they are mostly restricted to showing it in awards shows, like Jackman has and Tom Holland did recently:
By contrast in Bollywood movies everyone is expected to be that all rounder still, sing and dance and do stunts as those are the movies they make.
