The colours thrown out by The Jungle Club's oil-wheel differ from shot-to-shot when Cody and Templar chat.
Night time in the Caribbean is very warm, yet in the snake scene, Simon is sleeping in a bed with a sheet, a thick woolen blanket and a counterpane. He would have been far too hot with such bed covers.
The registration number (N95467) on the Grumman G21A Goose is a USA registration number and would not be used on aircraft located in the Caribbean islands.
In the opening scene, as Simon waits for Cody, the music is very clearly brass and woodwind and percussion. As Cody enters the club, the musicians are seen to be a steel drum band, with no brass or woodwind instruments in sight.
