"The Most Dangerous Game" and "Fantasy Island"

After watching the movie "Fantasy Island", I didn't have any questions. I understood all of the stories. The story about Paul Henley was pretty easy to understand.
Three similarities that I found were that, both in the book and the movie, the story takes place on a deserted island. Both characters are professional hunters and have a lot of background in what they were doing. Another similarity is that in both stories, humans were hunted rather than animals.
There were also a lot of differences, in the book, Rainsford was alone and in the movie, there was a lady with him. Another difference is that in the book, Rainsford didn't want to be haunted, but in the movie he wanted to be hunted and killed. Also, in the book there was only one hunter, General Zaroff. In the movie, there were three hunters. The hunters had "reasons" why they wanted to kill Paul Henley.
