Yes, "Sky High" is a Disney movie. Released in 2005, it is a live-action superhero film produced by Walt Disney Pictures. The story follows a teenage boy named Will Stronghold, the son of two superheroes, as he navigates high school for young heroes. The film combines elements of comedy, adventure, and coming-of-age themes, showcasing the challenges of fitting in and discovering one's own identity and powers.

As of now, there has been no official announcement regarding a sequel to "Sky High." The original film, released in 2005, has maintained a cult following, and while fans have expressed interest in a sequel, Disney has not confirmed any plans for "Sky High 2." In interviews, some cast members have shown enthusiasm for the idea, but without an official statement from Disney or the filmmakers, a sequel remains uncertain.

"Sky High" is a standalone movie released in 2005, and there is no series directly associated with it. If you're referring to a potential series or sequel that has been announced after my last update in October 2023, it’s best to watch the original movie first to understand the characters and the world they inhabit. However, if there is a new series, it may have its own storyline that doesn't require prior knowledge of the movie. Always check the specific details of the series for the best viewing experience.

"Sky High" is available for streaming on platforms like Disney+. You can also rent or purchase it on services such as Amazon Prime Video, Google Play Movies, and YouTube. Availability may vary by region, so it's a good idea to check your local streaming services for access.
