You know what's weird? About half of the way through Sky Captain and the World of Tomorrow—the retro-future film in which Jude Law and Gwyneth Paltrow save the world from robot attackers—I realized that so far nobody had eaten anything. I made a bet with myself that nobody would, either. I mean, what is retro-future food? In case you haven't seen the movie, Sky Captain has the look and feel (mostly computer generated) of a film about the future made in the '40s. Somehow, it seemed unlikely that the director would sway the viewers' attention with the introduction of pot roast pellets or tuna casserole injections. Would Sky Captain pause before climbing into the cockpit, pull out a small plastic case and place on his tongue a dissolving film, not a breath-freshening mint, but one that releases the full flavor of turkey and all the trimmings? Probably not. The only two foods I did notice in the film (and honestly, I had to go to brandcameo.com to recall them) were Coke and Dubble Bubble. Maybe imagining Jetsons-style meal-replacement mints was silly. If there's any food that will make it into the future, it's certainly going to be Coke. And if Dubble Bubble, the gum with the flavor that disappears after a minute of chewing, is still going strong after 80 years, it'll still be here when the giant robots come to kill us all.
