Glass Onion the movie is, of course, a reference to the song “Glass Onion” on the Beatles’ so-called White Album. The movie is a lot of fun, with Daniel Craig reprising his role from Knives Out. A parallel between Craig’s character, consulting detective Benoit Blanc, and Sherlock Holmes, is revealed in a cameo appearance by another British actor.
The premise of the movie borrows from Agatha Christie’s famous story “Ten Little Indians,” which was retitled “And There Were None” in the United States. The reference to “Indians” was itself changed from something else, as explained in the Wikipedia entry for the story.

The movie also borrows from the video game Myst, which is coming up on its 30th anniversary. The comparison is made explicit in a 3D tour of Glass Onion Island.
The island doesn’t exist, but the special effects making it seem like a real place are utterly convincing.
Taking the virtual island tour doesn’t require a Netflix account.
