You can also decorate your space to match the theme, and you might want to consider serving food and drinks that are related to the movies you're watching. If you're just picking a random selection of movies, you can still make it a fun and special event. You can set up a projector and screen in your backyard, or you can rent out a movie theater for the day. You can also invite other friends and family members to join in on the fun.
