Slightly off topic but felt like sharing with y'all 😃
My brother once pointed out that during a bollywood song and dance routine, focus on the side kicks than the main actors. Well, it does guarantee some laughs 😆 Agreed most of the side kicks are actually dancing better than the stars but some have that plastered smile and that desperation ki shayad iss dance mein woh notice ho jaye toh aglee fillum as a hero/heroine pakki 😆 😆 Try paying attention to the extras next time you come across a bollywood song and dance number. It's lot more fun than watching the stars 😆
That's not always true. Of course if someone from them gets an offer for a film most of the chances are s/he will accept it, but most of the times especially nowadays the dancers are professional dancers from some of the famous troupes in the city. They don't go there to become a film star, they go there to give a good performance. Most of the chances are their dance company will try to tie up with some of the stars or musician or some entertainment house so that whenever they undertake some world tour or something like that, they'll be the one performing along with them (that's not to say that they don't perform abroad on their own).
What you said holds true more for the extras while acting. They are really fun to watch if someone actually focuses on them. Especially when they have to do some movement or some small stuff but no dialogue.
