What is the name of that Mor Chit theatre? Never found one in that area. The only one more or less close by was the Amornpat - and that one is closed.
The only cinema's I know still open are the Paholythin Rama and Prince. Prince is in Chinatown, on Thanon Yaowarat. Within walking distance of Saphan Taksin skytrain station.
I think we all regret it very much, but suck cinema's in Bangkok are going the way of the dodo.
