Visible crew/equipment: After Doctor Strange experiments with the magical doorway in the Sanctum Sanctorum, he leaves it on a desert view and we cut to a shot panning across all the artifacts. At the very start of the shot on the right hand side of the screen is a crewmember standing in the shadows looking bored. Really blatant if you turn up the brightness, but easy enough to spot if you know what you're looking at. (00:56:00)
Visible crew/equipment: After Colossus and Negasonic Teenage Warhead leave the manor, the scene cuts back to the bridge where several gunmen are shown exiting cars and begin approaching Deadpool. In one of the shots during this, a gunman is shown exiting the passenger side of a car, with the camera placed behind him. In the shot, the reflection of a camera, cameraman and boom mic are visible in the wing mirror. (00:10:15)
Visible crew/equipment: At the end of the film when Samantha enters the diner to meet Jack, the reflection of the outside glass door shows film crew members. Probably the Script Supervisor and Director. (01:48:36)
