While popcorn and M&Ms have been movie theater concession staples for decades, there's no reason you can't shake things up a bit. Upgrade the theater standard with a popcorn bar featuring flavors such as kettle corn and cheese, and mix-ins such as chocolate chips or your favorite movie theater candy if that's more your taste. And get creative with other food ideas. Prepare picnic-style options (or encourage your guests to bring their own picnic baskets), set up a taco buffet, or combine movie night with some backyard grilling. Make hot dogs and burgers, roast some marshmallows -- for s'mores or just because.
Also consider placing a few small, collapsible tables around for plates and glasses, particularly if you're serving more than finger foods. And if you're planning on serving adult beverages, keep in mind that just one 12-ounce beer significantly increases your chances of being bitten by mosquitoes [source: Shirai].
