Movies don't magically appear overnight. They take time to develop, shoot, and edit:

"Knowing was originally written by novelist Ryne Douglas Pearson and the project was set up at Columbia Pictures. Both Rod Lurie and Richard Kelly were attached as directors, but the film eventually went into turnaround. The project was picked up by the production company Escape Artists, and the script was rewritten by Stiles White and Juliet Snowden. Director Alex Proyas was attached to direct the project in February 2005."

OP read the script and decided to have some fun, and has probably been laughing since 2007. Case closed.
