There’s a scene with quite a bit of shouting (Walter jumping into the ocean out of the helicopter). Later, Walter is yelled at in Icelandic because a volcano is about to erupt and he doesn’t realize that he’s in danger. Not really screaming either time, just urgently trying to communicate
Not really, though Walter's new boss makes fun of him for zoning out a few times. In some dream scenes, Walter stands up for himself which one time, leads to a fight between the two of them.
No, but in one brief dream sequence, Walter is the size of a child, but he looks very old. This might unsettle some viewers, though it's mainly played as a joke.
A drunk man in a bar holds Walter’s face down and smashes a beer glass and goes like he’s going to attack Walter with the broken glass. Walter’s eye is the primary exposed part of his face so it may make people nervous that something will happen to his eye, but it doesn’t. Even though I’d seen the movie before and knew everything would be fine, it still made me a little anxious
No, but there is a short while where you think that a very important and valuable (not necessarily financially valuable) item has been lost, but later it’s revealed that the item was saved.
The main character frequently "zones out" and daydreams, to the extent of maladaptive daydreaming. We see his daydreams play out on screen, before he snaps out of it, sometimes realizing that people have been trying to talk to him. Some characters make fun of him for this, but they are not portrayed in a positive light.
I would say yes, because Walter Mitty seems to be experiencing maladaptive daydreaming, which is considered to be a mental health issue, and some other characters make fun of him for it. Those characters are not portrayed in a positive light though.
