why is a movie trailer called a trailer
Trailer (promotion) A trailer (also known as a preview or coming attraction) is a commercial advertisement for a feature film that will be exhibited in the future at a cinema, the result of creative and technical work. The term "trailer" comes from their having originally been shown at the end of a feature film screening.[1] That practice did not last long, because patrons tended to leave the theater after the films ended, but the name has stuck. Trailers are now shown before the film begins.
The Rocky Horror Picture Show The Rocky Horror Picture Show is a 1975 British-American musical comedy sci-fi horror film by 20th Century Fox produced by Lou Adler and Michael White and directed by Jim Sharman. The screenplay was written by Sharman and actor Richard O'Brien, who appears in the film, which is based on the 1973 musical stage production of the same title, with music, book, and lyrics by O'Brien. The production is a parody tribute to the science fiction and horror B movies of the 1930s through to the early 1970s. Along with O'Brien, the film stars Tim Curry, Susan Sarandon, and Barry Bostwick and is narrated by Charles Gray with cast members from the original Royal Court Theatre, Roxy Theatre, and Belasco Theatre productions.
