DOCUMENTARY FILMS Catfish, a documentary released in 2010, follows a young man as he enters an online relationship with a woman and then attempts to track her down in real life. The movie was a modest box office success but took on a greater life of its own when the filmmakers brought Catfish: The TV Show, a weekly investigation of online relationships, to MTV. The authenticity of some situations in both the film and TV show has been questioned, but that hasn’t stopped viewers from tuning in.
