The cats body is found at 39:30 and the boys lay on the ground with it with it at 39:50, skip to 40:05 to miss the scene. The cats body is floating in the liquid at 40:35, left in the living room for the mother to see. The scene ends around 41:33 after the mom dumps cockroaches in with the cats body. Got a little wordy here but 39:30-41:33 features the dead cat until the body and liquid is used as fuel for the fire in the 1:25:00 range and is zoomed in on while on fire from 1:29:30 to 1:29:50
The boys keep a lot of cockroaches in a tank and they're seen throughout the movie. In some scenes they're crawling into someone's mouth and out of cuts in their body
There is a scene where the mother pulls at a hang nail on her toe and it peels up further on her leg to reveal a black inside. There's no blood, but it can be seen as squicky.
The mother is bound to a bed and the twins torture her. They burn a hole into her face, glue her mouth together and then cut it open with scissors, grind into her gums with tooth floss, and a few less gruesome tortures
It depends on your definition of "excessive," but there is some blood and depictions of injuries. However, it isn't like some super gory movies, like the Friday the 13th and Saw series.
SPOILER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Lukas is actually dead and it is not revealed How he died until the end of the film.
It happens at the end of the movie when Elias runs from the barn. You can kind of figure when it will happen as he's gagging while running. It is visual and audio but it's not that bad as it is kind of dark. It can be triggering.
the mom and one of the twins have some questionable and rather violent trauma responses and coping skills but it's only revealed that those are from probably ptsd at the end of the movie
When the boys follow the meowing sound, they enter an old mass grave, stepping over piles of bones. Not antisemitism, but combined with setting (Austria), the visual might be triggering
Yes, the mother has her mouth glued shut and then cut open with scissors, resulting in bleeding. The boys have a dream of cutting her abdomen open vertically, but you can't see much gore as a result of all of the cockroaches inside her. The boys fist fight and have nosebleeds
