I saw Southland Tales recently and was kind of blown away by it. It's not exactly a good movie, but it's big and weird and ambitious as all get out. The casting is bizarre and inspired. I'm still processing it, really.
This is one of my favorite moments in the film, when army sniper Justin Timberlake--who is clearly post-traumatic--climbs off his sniper's perch in Santa Monica and scores some batshit drugs that have been boiled off a rift in time/space. He takes the drugs and has a low-brow musical number and a completely honest looing moment of guilt at the end. His expression at the end of teh number floored me. I'd seen it so many times before on the faces of high-school drunks at the end of a binge. It's the look of reality rising up to smack you in the face with all of your regrets and shame.
There's also a weird segue in the film where a stone cold Jon Lovitz acts out a bit from 'Flow My Tears, The Policeman Said."
