What we see on screen isn't always what happened on set, especially when the scene involves steamy, intimate moments.
Be it a tender love scene or a racy, explicit one, most such sequences are filmed with dozens of crew members present in the room. Moreover, they often run into awkward accidents, prop faux pas, and even mild to severe injuries.
The audience only learns about these incidents when the cast or crew opens up about what happens on the other side of the camera.
