Ascended Fanon: In the novel, Eli and Håkan's relationship is fairly well spelled out, but in the original Swedish film, their past is left ambiguous, leading those who hadn't read the book to speculate that Håkan was once a boy like Oskar whom Eli had seduced. Let Me In directly went with this interpretation. This however never set well with Lindqvist who as mentioned not only made it clear in the book but even wrote a side sequel short story to show Eli turned Oskar.

Corpsing: A minor case when Eli and Oskar first meet. The actors trip over each other's lines towards the end of the scene and Eli visibly stifles a laugh. It was at the end of a very long shot with a minor stunt so ended up getting left in, but luckily it made some sense in context anyway.
Playing Against Type: Per Ragnar (Håkan) is most well-known to Swedes who remember The '80s as a feel-good Saturday morning TV host.
Suppressed Mammaries: Happened to child actress Lina Leandersson - she was a rare averted case of Dawson Casting, being a 13-year old playing a 12-year old, but puberty hit her hard during the latter half of the shoot. She grew outwards so quickly the wardrobe department could barely keep up and the bindings used to keep her both age-appropriate and ambiguously gendered are clearly visible during some of the outdoor shots.
Series Examples
Actor-Shared Background: Like their characters, Demián Bichir (as Mark), Madison Taylor Baez (Eleanor) and Fernanda Andrade (Elizabeth) are all Latinos. Further, Mark says he's from Mexico originally, like Bichir is.
Disowned Adaptation: John Ajvide Lindqvist revealed that Hammer tricked him into signing away the television rights and is not getting paid for the show. “The only thing I've seen is the trailer, where there is some from the book and otherwise it's general vampire nonsense.”[1]
What Could Have Been: There was going to be a TV series that would have aired on TNT, but they passed on the pilot. Like with the American movie, it would have changed the characters' names (with the exception for Eli). One major difference between all the other incarnations would be that Oskar (called "Henry") and his bullies would have been 16-years-old instead of 12.
