Trivia: According to Michael Bay, Travis Van Winkle's Trent is the exact same Trent from the Transformers movie, meaning that both movies take place in the same universe.
Suggested correction: This info has been proven to be wrong. In Transformers, Travis Van Winkle plays Trent DeMarco, while here he plays Trent Sutton.
While I don't think Michael Bay ever directly said they exist in the same universe (if he did, I can't find it, so a link to him saying it should be provided). However, the films, as is, never reveal Trent's last name. For Friday the 13th, "Sutton" comes from a deleted scene, and "DeMarco" comes from the novelization of the "Transformers" film.
To add, the trivia never stated what Trent's last name was. Only that they were the same character.
Trivia: When Ann and Eddie are on their date, Ann reminds Eddie of his firing from the Daily Globe. In the Spider-Man comics, Eddie Brock was a reporter for the Daily Globe, a rival newspaper of the Daily Bugle. In the comics, a string of murders were being carried out by a serial killer named the Sin-Eater. Eddie interviewed a man who claimed to be the Sin-Eater but Spider-Man captured the real one and the man that Eddie interviewed was found out to be a compulsive confessor. This incident caused Eddie to get fired from the Daily Globe and sometime after becoming Venom, moves to San Francisco after agreeing with Spider-Man that they will not bother each other on the condition that Eddie no longer commits any more crimes.
