In Scream (1996), as Tatum starts realizing the severity of the situation and that Ghostface isn't pulling a prank she says, "Cut, Casper. That's a wrap!"
What is the meaning behind this line? Is it referencing something/someone? Who is "Casper" here?
Scream movie series is a satirical take on traditional horror and thriller movies. They contain many meta references to famous movies in those genres. So this is a direct reference to the character Casper the ghost from the movie with the same name. Also, note that Scream 1 came out in 1996, just a year later after Casper the movie was released, so the reference is obvious.
