In this hilarious tweaking of the fairy tale, "The Princess and the Pea", Queen Aggravain has ruled that none may marry until her son, Prince Dauntless marries. However, she has managed to sabotage every princess that come along. When Sir Harry and Lady Larken learn that they are going to be parents, wed or not, he goes off to the swamps and brings back Princess Winnifred ("Fred" to her friends). The queen is horrified and immediately begins to scheme, but Winnifred, with some help from Sir Harry, the King, and the Jester, isn't going to be quite so easy to get rid of.

How to Watch Once Upon a Mattress Legally and Safely

If you want to stream Once Upon a Mattress through reputable and legal services, there are a few good options depending on where you are. Subscription platforms like HBO Max, Disney+, Netflix, Amazon Prime Video, and Apple TV+ sometimes carry Once Upon a Mattress films or related DC titles—though availability depends on your country.

If you’d rather not commit to a subscription, there are ad‑supported, free (but legal) platforms such as Tubi, Pluto TV, Peacock or Crackle (where available in your region) that occasionally host superhero films.

Lastly, don’t forget about library‑linked streaming options like Kanopy or Hoopla (if your library or university is registered), and official uploads by film distributors on YouTube—these can also give you legal access to classic movies.
