Hi there, Maggi!
Disney's Hollywood Studios is the home to movies and magic, and face paint is a natural fit. Near the former Journey Into Narnia exhibit, just adjacent to
Toy Story Mania, you'll find the Special F/X storefront, where Guests can get their faces painted like animals, fairies, and a variety of movie-themed characters.
Several
Star Wars characters are available, which certainly fits the popularity of the
Star Tours attraction (and annual
Star Wars Weekends!).
While there are currently no Marvel licensed properties available, the menu choices include superhero "types" that the talented makeup artists can easily tweak into a more specific look. Copyright issues might prevent an entire duplicate of a Spider-Man face, but you'll be able to make something work to everyone's satisfaction.
Have a wonderful time!
See you later, celebrator.
