Visible crew/equipment: There is a scene where Michael Myers is hiding behind a hedge bush and Laurie and her friend go to investigate. Laurie turns around and talks and you see cigarette smoke go by the camera (John Carpenter admitted on the commentary track that he was smoking a little too close to the camera that day). (00:24:10)
Visible crew/equipment: Just before Laurie stabs Michael with the knitting needle you can see that one of the window shutters is open and that the wind is ruffling the curtain. When the camera gets closer and the curtain is out of the way you can see the huge fan in the studio being used to simulate the wind outside. (01:19:50)
Visible crew/equipment: When Annie is locked in the laundry room, there's a scene where the phone is ringing incessantly and the camera pans slowly to the right showing little Lindsay Wallace who's too busy watching television to answer the phone. If you watch this scene in widescreen, you'll see a crew member lurking in the shadows (left side of the screen) on the wall. It appears they are trying to avoid being seen. (00:47:10)
Visible crew/equipment: During the opening sequence, the scene is shot in first-person point-of-view from the young Michael Myers. As he walks through the house, the shadow of the camera can be seen several times. After he picks up the knife in the kitchen, the camera's shadow is visible on the door frame leading into the dining room. It can be seen again just before he turns to go upstairs. (00:04:05)
Visible crew/equipment: Just after Michael has picked up the knife, a stage light can be seen in a silver pot. This is as he walks into the next room. (00:04:15)
Visible crew/equipment: At the end of the opening murder scene, when Michael's father takes Michael's mask off, you can see the shadow of the camera cast on Michael's father as it pulls away. (00:06:35)
Visible crew/equipment: In the scene where Dr. Loomis makes a call to Haddonfield police in a phone booth by the train tracks, you can see a reflection of a crew member in the phone booth glass.
Visible crew/equipment: When the camera is zooming in on Laurie in school, the camera's shadow can be seen over the students it passes. (00:15:30)
Visible crew/equipment: When Laurie is trying to escape from the kitchen, you can see some kind of blue light in the top left corner making it look like it's light from the moon.
Visible crew/equipment: After Lynda and Bob make out on the couch, they both start to go upstairs. Lynda trips over the dolly track and Bob steps over it. (01:01:50)
Visible crew/equipment: When Laurie tries to escape Michael from the kitchen, she breaks the glass. You can see a second hand break the glass in front of Laurie's.
Suggested correction: You are incorrect, but it's an understandable mistake to make because the scene is very dark. It's hard to see, but Laurie actually uses both hands to break the glass... she puts them together and then slaps them through the window in a quick, fluid motion. (If you go through frame-by-frame or in slow motion, it's much, much easier to see.) That's why you're seeing two hands. It's not a crew member's hand... it's Jamie Lee Curtis' other hand.
Visible crew/equipment: When Bob gets impaled, Michael steps back to observe. Crew lights are quite visible behind Michael's head as the camera pans back. (01:05:50)
Visible crew/equipment: As Laurie heads up to the porch, the shadow of the boom is visible above the door.
