Date will be the same day, however since we are in different
time zones, Singapore sees it first.
New york in the east coast is 12 hours behind, Houston in
central is 13 hours behind, and LA is another 2 hours behind
Houston.
As to whether they use disc or film I dunno leh, I grew up in
the days cinema uses film and project to the big screen from a room
behind the theatre. Nowadays I don't see that room anymore, it just
magically appear on screen.
