A blast from the past.
Released in 2006. A Scanner Darkly features a bunch of people: Keanu Reeves, Robert Downey Jr., Woody Harrelson, Winona Ryder, Rory Cochrane, and more. Directed by Richard Linklater.
The plot: In a totalitarian society in a near future, the undercover detective Bob Arctor is working with a small time group of drug users trying to reach the big distributors of a brain-damaging drug called Substance D. His assignment is promoted by the recovery center New Path Corporation, and when Bob begins to lose his own identity and have schizophrenic behavior, he is submitted to tests to check his mental conditions.

An really good example of using rotoscoping to enhance the storytelling.
Some of you will remember it’s predecessor, Waking Life (2001), which stars Ethan Hawke. Also directed by Linklater in which he first used rotoscoping in a feature-length film release. Again, the script suits the technique. In this one, a man walks through a dream and engages in existential and philosophical conversation with other characters in true Linklater fashion.
