Uwe Boll is a German filmmaker. He came to prominence during the 2000s for his adaptations of video game franchises. Released theatrically, the films were critical and commercial failures; his 2005 Alone in the Dark adaptation is considered one of the worst films ever made. Boll's subsequent projects, released during the 2010s, were mostly released straight to home media. After retiring in 2016 to become a restaurateur, Boll returned to filmmaking in 2022. His films are financed through his production companies Boll KG and Event Film Productions.
