Subway has announced that it gives free tickets to the Disney film Mary Poppins Returns, in theaters December 19, and has released a new commercial, as well.

“Their imagination is endless. Luckily with Fresh Fit for Kids, so are the possibilities. Plus, their meal gets them into the movie” onscreen lines read on the 30-second spot, which features a boy and a girl finding in a Fresh Fit for Kids take-away bag a movie ticket to Mary Poppins Returns.

Starting today, participating Subway restaurants in the U.S. will give families not only the possibility to enjoy great-tasting meal options, but also the chance to get a free children’s movie ticket, up to $11 total ticket and convenience fee value, to Mary Poppins Returns in theatres. Inside every kid’s meal there will also be one of four collectible Disney’s Mary Poppins Returns-themed greeting cards.

The tickets can be used from December 19 through January 7, 2019, or when the movie is no longer in theaters.

A Fresh Fit For Kids meal allows children to customize their meals by choosing one of four sandwiches made with wholesome ingredients, including lean meats, whole grain certified bread, and fresh veggies like lettuce, tomatoes, and cucumbers. They also choose from no sugar added beverages like 1% low-fat milk or Honest Kids juice. Each kids’ meal is also paired with a 100% fruit side.
