Television films
The following are television films that never saw theatrical release.

Pilots
Some television films have functioned as pilots or backdoor pilots for a subsequent TV series, but most of them start off as the first regular episode of a series overall.

Reunion films
Many American TV series have had TV films, usually filmed five or more years after the run of the original series, which reunite the cast of the series for a new plot. In some cases, there has been an entire string of such films, including for the detective shows Perry Mason (1957-1966; 30 films from 1985 to 1995), The Rockford Files, (1974–80; eight films from 1994 to 1999), and Hart to Hart (1979-1984; eight films from 1993 to 1996). In at least one case, with the 1988 Get Smart reunion film Get Smart, Again!, the success of the TV film eventually led to a brief 1995 revival of the series.

There have also been many television reunion specials, in which some or all of the original cast is brought together for interviews and clips.

Specials
Television series that have had standalone episodes as films, from continuations and resolutions of storylines through expanded installments with similar miscellaneous purposes, and specials based on their respective characters and elements for alternative reasons of otherwise.

Programs re-edited for release as feature-length films
One or more episodes from the following television programs were edited together for release as a feature film. Some of the films add new material, and others do not.
