I absolutely love The Great Gatsby. But I can't help but think that Gatsby called Nick "old sport" too many times instead of his actual name. He only said "Nick" once and I think that seriously undermines the friendship they have.
This is Gatsby's funeral in the movie. There is only Nick goes to his funeral, but in the novel, there are three people take part in. One is narrator, one is Owl-eyed glasses, and another one is Gatsby's father.
