(colloquially also known as It's a Royal Knockout) was a one-off charity event which was shown on British television on 19 June 1987. It followed the format of It's a Knockout (the British version of Jeux Sans Frontieres), a slapstick TV gameshow which was broadcast in the UK until 1982. The event was staged on the lakeside lawn of the Alton Towers stately home-cum-theme park. However, the event used its own specially created immersing set, meaning that the location was not very recognisable in the TV broadcast. Although regarded as a failure, a similar show (without royal involvement) was made the following year at Walt Disney World in Florida, featuring teams of celebrities representing the UK, USA, and Australia.

How to Watch The Grand Knockout Tournament Legally and Safely

If you want to stream The Grand Knockout Tournament 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 The Grand Knockout Tournament 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.
