A few people have sent me emails commenting on a scene in the film in which Bruce James, playing the flight attendant, throws a snake into the onboard microwave. For a few moments you can see that this particular microwave in fact has ‘Snake’ as a cooking option. You may have noticed it in fleeting during the theatrical release, but the DVD allows for so much greater clarity (and screenshots):

During the audio commentary to the scene (it starts at 43:45 by the way), director David Ellis comments that this microwave was actually a prototype and, before long, all airlines will be equipped with them.

UPDATE: David Ellis set me straight: this was NOT in the original theatrical release and was added to the DVD as something that “only the fans would catch.”
