Portions of the video of Grace Stamper and A.J. Frost's wedding are shown during the final credits.
All initial UK '12' Certificate videos came with the full promo video for Aerosmith's: "I Don't Wanna Miss A Thing" before the film started. The video only came with the limited widescreen or even more limited 'double feature' boxed video with 'The Making of Armaggedon' as a bonus video. Also some outtakes (1 per character) were featured at the very end of the credits with text underneath saying 'In loving memory of <character's name> who gave his life saving our planet.' (The outtakes only came with the initial copies on video.)
