Context: As One (; lit.  "Korea") is a 2012 South Korean sports drama film starring Ha Ji-won and Bae Doona.  It is a cinematic retelling of the first ever post-war Unified Korea sports team which won the gold at the 1991 World Table Tennis Championships in Chiba, Japan.  Director Moon Hyun-sung used the foundation of true events to tell the story of a team that united a divided nation for the first time in its painful history. The Tokyo Sports Film Award for Best Actor is an award given at the Tokyo Sports Film Award.  This award is not only given to a person, but also a film character such as Godzilla in 1992. A sports film is a film genre that uses sport as the theme of a film.  The sports film is a production in which a sport, sporting event, athlete (and their sport), or follower of sport (and the sport they follow) are prominently featured, and which depend on sport to a significant degree for their plot motivation or resolution.  Despite this, sport is ultimately rarely the central concern of such films and sport performs primarily an allegorical role.  Furthermore, sports fans are not necessarily the target demographic in such movies, but sports fans tend to have a large following or respect for such movies. The surf documentary Lost Prophets – Search for the Collective debuted in fall of 2009 with two showings to crowds of over 1,000 surf and action sports film fans in Laguna Beach, California.  After the premiere, the film embarked on a 15-city tour throughout North America, wrapping in late January 2010.  Lost Prophets was nominated for "Best Cinematography" for Surfer Magazine's Surfer Poll/Video Awards '09, “Best Film” at X-Dance Action Sports Film Festival (the action sports entity of Sundance Film Festival) and won “Best Original Score” for "its moody, highly unique music that created a soulful tone for the film about nomadic surfers."
