Have the child choose their favorite movie or choose a movie that you think will be fun. Then have the children/guests dress as their favorite characters in the movie. The decorations would consist of props from the movie. The food served would relate to the movie somehow.  Example:  Theme: The Lion King Costumes: Simba, Timon, Nala, Pumba, Scar, etc. Decorations: You can pick up Lion King decorations at almost any Party Favor store or you can make your own. For example, make paper cut-out animals and trees. Be creative. Food: Gummi worms & bugs (relating to Timon & Pumba), cups of dirt & bugs (a dessert involving chocolate pudding, oreos, & gummi worms), jungle punch (fruit punch), sandwiches cut out in shapes of bugs or characters of the movie, etc.
