There was a trilogy of books in the early-mid 80s called the 'Cineverse Cycle' by Craig Shaw Gardner where an average Joe discovers that pretty much every TV Trope you see on the big screen exists in some form or another.
There's a 'Mad Scientist ' world, a 'Film Noir' world that's back and white complete with a Sam Spade character and voiceover, narration, a 'Talking Animals ' world, a 'cartoon world', etc.
I really don't remember much about them, but two things stand out - the creature from the swamp that the hero and damsel in distress encounters looks like a cheep gorilla suit with a zipper up the back and the 'swamp' looks like a studio set with plastic plants and trees; and 'singing western world', where the hero gets on his horse and tries to ride off into the sunset only to discover that the backdrop keeps moving but he's not making any progress (like the horse is stuck on a treadmill) because he has to sing 'the story so far' in order for the horse to move.
A trilogy of movies like that where they explore every cliche would be fun to watch.
