There are two "21 Jump Street" movies. The first, titled "21 Jump Street," was released in 2012 and starred Jonah Hill and Channing Tatum as undercover cops who infiltrate a high school. The sequel, "22 Jump Street," followed in 2014, continuing the duo's adventures as they go undercover at a college. Both films are comedies based on the 1987 TV series of the same name.

Johnny Depp has expressed mixed feelings about "21 Jump Street," the TV series that launched his career. He felt that the show, while popular, was sometimes more focused on style than substance, and he was not particularly fond of the fame it brought him at a young age. Depp has mentioned that he was uncomfortable with the show's formulaic approach and the typical portrayal of teenage issues. However, he has also acknowledged its cultural impact and the nostalgia it evokes for fans.

"21 Jump Street" is not based on a true story but is inspired by the 1987 television series of the same name. The show featured a group of young-looking police officers who went undercover in high schools to investigate crimes. The movie, released in 2012, takes a comedic approach, following two officers, played by Jonah Hill and Channing Tatum, as they revisit high school to uncover a drug operation. While it incorporates elements of real-life high school experiences, the plot and characters are fictional.

As of October 2023, the "21 Jump Street" movies are not available on Netflix. However, streaming availability can change frequently, so it's a good idea to check Netflix directly or use a service like JustWatch for the most current information on where to watch the series. You might find them available on platforms like Amazon Prime Video or Hulu, depending on your region.
