Is it possibly Heath Ledger accumulated some demons around him after playing the joker?

It definitely didn’t help him.

I would say more likely the sleep depravation and prescription meds accumulated around him.
A real shame, I wasn't sad he died until I saw that performance.

I don't think so. Suicide isn't very Jokery. Getting someone else to suicide would be.

Maybe you’re too into the character that you are 👀

Is that the man who played joker in the dark knight
