i was reading a book on scriptwriting and it was explaining about setting up last-act payoffs and for an example started describing a suspense movie i’ve never seen, where in the first act the cop main character wants to hide his job from the love interest and so hides his big official police marksmanship trophy under his bed

and i was like, okay, sure, now the end of the movie’s all set up so he can do some expert high-stakes sharpshooting, but then it goes on to describe how in the climax the villain tries to murder the hero in his sleep, and in the struggle the hero… reaches under his bed and beats the villain to death with the trophy

so i guess chekhov’s gun has a fun new corollary: if there’s a gun on the wall in the first act, in the third act you can take it down and just fucking wail on someone with it
