In the movie Oppenheimer Jack Quaid plays Richard Feynman and at one point he raises the bongos. This is a reference to the fact that Richard Feynman was a badass and the film should have actually been about him instead of three hours of being called a commie and smoking a cigarette.
In Justice League (2017) and The Flash (2023) [Not pictured because I can't find a picture of the scene] there is a scene where the lasso of truth makes the main characters blurt out embarrassing secrets. Even though that's not how the lasso works. This a reference to me caring too much
In Oppenheimer (2023) there is a plot hole, the bombs must be released from planes. This is a cheap and inefficient method that could risk the plane and it's pilot. This could easily be fixed by finding the missing link between artillery & infantry... With a sort of “Metal Gear", if you will.
