This making of ... mixes the usual roster of movie snippets, archival footage, and interviews. We hear from Mimi Leder, screenwriters Bruce Joel Rubin and Michael Tolkin, and we also get a few quick 1994 snippets from scientific authorities who discuss some realities behind the comet-related prospects. We learn about the project's origins, writing the screenplay and research, how Leder came onto the film and her preparation, developing the characters, and casting. Also included is a look at the process of condensing the script from a three-hour epic to a more manageable two-hour run-time.
