Bozo (2013)

Set in Nagano Prefecture, the movie stars Shingo Mizusawa (8000 Miles) as an awkward 28-year-old temporary factory worker named Kaji; a character partially modeled after the perpetrator of the 2008 Akihabara massacre. His social interactions are limited to his postings on internet message boards until he starts hanging out with a co-worker named Tanaka (Shohei Uno) who suffers from the debilitating sleep disorder narcolepsy. The pair become involved in a predicament when they attempt to protect a girl named named Yuri (Ai Tamura) from their other co-worker Okada (Yasushi Fuchikami).

Unfortunately the movie Bozo is not yet available on HBO Max.
