The idea for Advent Children came about when script writer Kazushige Nojima wrote a script that was "just a story about Cloud and Tifa and the kids". Visual Works, a company that has developed CG films for Square, picked Final Fantasy VII as the theme for a presentation that they were going to create. Square's research and development department worked with them on its launch, and director Tetsuya Nomura joined the crew after producer Yoshinori Kitase called him. Advent Children was originally going to be a game sequel, but Nomura stated that it was not possible due to a number of factors. However, the development team decided to stick with the original plan and work on it as a movie production.
