Where was the Man with the Golden Gun Filmed?

Famous Bond Director Guy Hamilton started filming the Man with the Golden Gun on location in Hong Kong in November, 1973 before heading to Bangkok and then Southern Thailand in 1974. 

The external shots of Scaramanga's island lair were filmed in Phang Nga Bay and the islands of Ko Khao Ping Kan and Ko Tapu aka James Bond Island. 

At that time the area was not yet a famous tourist attraction and there were limited facilities available for the cast and crew of the movie with everything including food and water having to be flown in.
