A feature film is a film (also called a movie or motion picture) with a running time long enough to be considered the principal or sole film to fill a program. The notion of how long this should be has varied according to time and place. According to the Academy of Motion Picture Arts and Sciences, American Film Institute, and British Film Institute, a feature film runs for 40 minutes or longer, while the Screen Actors Guild states that it is 80 minutes or longer.Nostalgia is a sentimentality for the past, typically for a period or place with happy personal associations.
Nostalgia is triggered by something reminding an individual of an event or item from their past. The resulting emotion can vary from happiness to sorrow. The term of "feeling nostalgic" is more commonly used to describe pleasurable emotions associated with and/or a longing to go back to a particular period of time, although the former may also be true.
