The first moving picture is often credited to "Roundhay Garden Scene," a short film directed by Louis Le Prince in 1888. It lasts just 2.11 seconds and features four people walking in a garden. However, the first commercially successful moving picture is considered to be "The Horse in Motion" (1878) by Eadweard Muybridge, which used a series of cameras to capture a galloping horse. Both contributions were pivotal in the development of motion pictures, leading to the film industry as we know it today.

A movie that follows a previous movie is typically called a "sequel." Sequels continue the story or expand on the characters and events from the original film. They can explore new themes or further develop existing ones, and they are often made to capitalize on the success of the first movie. In some cases, sequels may also be part of a larger franchise, which can include multiple related films, spin-offs, or adaptations.

A still image from a film is commonly referred to as a "film still" or "stills." These images are typically captured during the filming process and can be used for promotional purposes, in reviews, or as part of a film's marketing materials. Film stills serve to convey the visual style, themes, and characters of the movie, providing audiences with a glimpse of the cinematic experience. They can be iconic moments or representative scenes that highlight the film's essence.
