Trivia: The huge crash that starts the film takes place at McKinley Speedway. The students who die in Final Destination 3 attend McKinley High School, and there is an running gag in that film that one of the students targeted for death is also named McKinley.
Trivia: In the end scene (right before the lead characters go into the cafe shop) you can see a bus drive past with the number 180 printed across the top. The number 180 was a significant number in the first three Final Destination films.
Trivia: The theater number towards the end where Lori and Janet go, is an unlucky 13.
Trivia: Shirley Walker composed for every FD film up until this point except this one. She died in 2006.
Trivia: The significant number from the previous three films, 180, is also seen at the beginning of this film - it is the section number that everyone is sitting in during the race.
Trivia: When Nick is trying to save his friend Hunt, he drives past a bus stop that has an advert for "Clear Rivers Water". Clear Rivers was the name of Devon Sawa's girlfriend in Final Destination and Final Destination 2.
Trivia: A number of video games feature The Final Destination posters: Saints Row 2 has posters around the city taped to walls and poles, Skate 2 features billboards with posters on them, and Mercenaries 2: World in Flames added billboards with the movie's logo. Tom Clancy's Rainbow Six: Vegas 2 also features the teaser posters hidden around certain maps with the main goal to find all of the posters for a chance to win $1,300.
Answer: Janet never died before the premonition, most likely case scenario would be that since both Lori and Janet were at the theater death would be more likely to "kill to birds with one stone" which would mean that he wouldn't care about the order. Death would just want to get it done. Same scenario for Nick, Janet and Lori's deaths at the cafe, and Ashley and Ashlyn's deaths from FD3.
