No one has said DeNiro in Raging Bull yet??? Maybe Taxi Driver too.
Absolutely Nightcrawler with Jake Gyllenhaal.
Guy Pearce in The Rover.
No spoilers really, just 6 minutes of the opening scene (a bit of the opening is cut in this clip, dude shows up in his car and stops in for a drink, it cuts in with him already in the bar)
It is a great, morally bankrupt, post economic collapse Australian flick about a man at the end of his rope. Discovering the protagonists motivations is what makes it work.
If the inciting incident in the clip isn't grabbing you, then this one isn't for you. And just try to look past the fact that the truck should be really fucked after a roll over like that. They had a very low budget to keep. Focus on the story. This is a Shakespearean style story. Take it at face value.
Brawl in Cell Block 99 is a perfect example, Vince Vaughn as the angriest man alive with no way to vent it.
Casey Affleck, Manchester By The Sea
Leo in most of his movies, especially Revolutionary Road and The Departed
imo, Takeshi Kitano does this really well in Sonatine, one of my all-time favorites.
I don't know if Michael Shannon in *Take Shelter* counts.
