Felix Leiter is a main character in the book version, yet he does not make an appearance in the film version.
The name Scaramanga came from a Greek man Fleming knew named Pandia Scaramanga whom he met on the island of Hydra and in whose island house he stayed in. Fleming actually asked permission to use the name, letting him know that he would be a villain. Mr. Scaramanga, being a superstitious man, replied: "I certainly do not mind your using my name but please do not kill me."
The scene where Scaramanga and 007 stand back-to-back, with their guns drawn, is a reference to the John Wayne western The Comancheros (1961). The only difference was that Nick Nack counts to 20, instead of 10.
