Genres and Topics
A mondo film (from the Italian word for "world") is an exploitation documentary film, sometimes resembling a pseudo-documentary and usually depicting sensational topics, scenes, or situations. Common traits of mondo films include an emphasis on taboo subjects (such as death and sex), portrayals of "foreign" cultures (which have drawn accusations of ethnocentrism or racism), and staged sequences presented as genuine documentary footage.
Topics are sub-genres and/or themes of any kind (romantic comedy, buddy, sports, etc.) that describe the plot of the movie you are looking for. Topics, however, are not keywords. If you search for a topic like "shark", for example, only movies in which sharks play a significant roll will appear, such as 'Jaws'. But not every movie that has a shark in it will be listed.
