What movie do you want made? If you got a pitch meeting with a producer and a guaranteed green light, what would you say?
Buddy movie where instead of becoming furious with his wife for cheating on him, the husband just becomes good pals with his wife’s boyfriend. Eventually the wife starts feeling left out as hijinks ensue. In a climactic scene, the boyfriend resists the wife’s temptations in order to help with the new business he and the husband have started together, which leads to the two guys stopping a mass shooter. The two become heroes and best friends forever. It turns out that the would be mass shooter is an ex of the wife who didn’t have a friend and just couldn’t deal.
This gives a “woman, therefore bad” movie troupe vibe. But if directed like the movie “That’s my Boy” and the script-writing improved a little bit, I guess it could be sold as one of those weird dark comedy movie. That being said, you’re gonna have to get Adam Sandler as the husband.
Not really going for a “woman, therefore bad” trope and I wouldn’t let the producers take it that way, as per the premise of the question. If I’m employing a trope, it would be “buddy good, even if he’s fucking your wife”. It’s a movie that puts friendship over toxic masculinity.
Forgot to add this before, but this kinda reminds me of the short film Holding, which is quite similar to your plot, minus the Adam Sandler shenanigans.
