In one scene, Joe Pesci pretended to bite off little Kevin’s finger, but he accidentally bit Macauley’s finger during filming and left a scar.
In the film, little Kevin watched a movie called "Angels With Filthy Souls". In fact, this "play in play" is not a real movie, but the crew spent an afternoon filming it, and the actors did not know what they were filming and where they were going to be used when filming the "play in play" .
In the scene where Daniel Stern was hit by an iron head-on, the director took a spring rope tied with a small camera and hit him in the face.

In the film, the light bulbs that Daniel Stern stepped on were made of candy, and the nails that he stepped on were also rubber.
The tarantula on Daniel Stern’s face was originally replaced by a mechanical spider, but the effect was very fake, so I chose a real tarantula to shoot; in the film, Stern’s screaming sound was added later. Go up, because if he really screamed loudly while shooting, the tarantula would most likely get a bite on his face.
Whenever Joe Pesci was very involved in the filming, he would inadvertently burst out the swear word "FUCK", thus forgetting that this is a family movie with underage and children in the audience.
