That's one of the dumbest movie theories I've ever heard.
No need for rudeness, Sir. However, it seems my "Theory" was taken a bit too literally. I'm not saying Arnold died because he was a smoker. I am saying that the fact he was a chain smoker in the movie telegraphs that he is likely to be one of the ones killed. I'm sure you realize assigning "impure" traits to eventual victims in "body count" type movies has been around since the inception of the sub genre.
So let's go over it again.
Gennaro - A lawyer (often the butt of jokes in movies) who as soon as it's revealed what Hammond has done sees nothing but dollar signs. Is cowardly and abandon two young children when the T-Rex appears. Dies. (The book version of Gennaro almost the opposite of the of the movie version. He eventually more leans more toward Grant and Malcolm's attitudes of the park and aids Muldoon in getting the park back in order after the power shutdown. And realized his culpability for the events as he did not more closely scrutinize what Hammond was doing. The book version of Gennaro lives.)
Nedry - Sloppy, Slovenly, fat, gluttonous, greedy, unscrupulos, obnoxious, a sabouteur and a thief. Dies (Nedry's personality, story and fate is largely unchanged from the novel.
Arnold - Nothing overtly wrong with him as a person, but is given a "bad habit" that is looked down upon many in the Politically Correct world. Dies (Again, Arnold does not die because he's a smoker, but the trait telegraphs the probably he will die. The Book version of Arnold was also a chain smoker and also is killed in the book).
Muldoon - The most cautious of all J.P. staff. Has observed and studied the raptors. Harbors grave concerns about their deadliness and believes they should all be destroyed. Yet he is a professional hunter which is also looked down upon in the Politically Correct world. Dies. The book verson of Muldoon lives. (Again, contrast Muldoon to Tembo from TLW who has an "awakening" near the end of the film and flatly refuses an offer from Ludlowe from an assumed game warder job at the planned San Diego Jurassic Park. Tembo survives).
Grant - A "Digger", uncomfortable with technology that may make the "purity" of digging obsolete. Has respect for dinosaurs and the deadliness of raptors. Isn't in it for the money. Harbors concerns and is critical of the park. Initially dislikes kids, but grows attached to Tim and Lex during their journey through the park. Lives
Ellie - Similar in nature to Grant, Harbors concerns about the park. Lives
Malcolm - Gravely concerned about the stability of the park and has no doubt that the system will break down. Vehemently critical to outright disgusted of what Hammond is doing. An environmentalist that stauchly believes in evolution and life "finding a way" loves kids, nearly dies trying to save Tim and Lex from the T-Rex. Lives. (Dies in the book, but death is ret-conned in the Novel of TLW that he was only errorenously reported dead)
Tim and Lex - Young children, no chance kids are going to be killed off. Both live.
Hammond - The book version of Hammond is along the lines of the stereotypical greedy capitalist. Some of the characteristics of the book Hammond were converted to the Movie version of Gennaro (Movie Gennaro's line about being able to charge whatever they want to tourists for admission to the park was originally spoken by Hammond in the book). Book Hammond dies in a similar manner to how Dieter from TLW dies. The movie version of Hammond is converted into a kindly, wide eyed, enthusiastic grandfatherly type figure. Irresponsibly used genetic technology but had grand and noble purposes (refutes his own book conterpart's notion of being able to charge highly expensive admission prices). Has an awakening at the end and accepts his failure. Lives.
Point is that the movie (certainly not the first and not the last) pretty clearly telegraphs who the survivors will be and who the victims will be.
