Transported into the movie or TV world

I’m looking for any movies, or show, that is about a character who is transported into the universe of a movie or TV show in their world. Examples are like Pleasantville or The Final Girls. Any genre is acceptable.

Last Action Hero
Stay Tuned

A Frank Dubosc vehicle by Yann Moix, if you dare : https://www.imdb.com/title/tt1130984/

I personally didn't bother.

The Purple Rose of Cairo may or may not qualify. Also, possibly Wandavision. Depending on the limits you put to your definitions.
