PRODUCTION DON’T’S

1. Don’t park your car in the middle of a shot.

2. Don't cough out loud during a take. The fear of doing this is so mortifying on set that people have been known to risk unnecessary Heimlich maneuver to avoid being caught coughing and ruining a shot.

3. Don't ask really stupid questions at the wrong time. It's always the wrong time. And stay away from the video monitor unless the director wants you there. Instead, wander around trying to appear purposeful.

4. Don't show up unexpectedly where a meeting might be assembling. Avoid all huddles. Unless it's one you're supposed to be in.

5. Don't let your portable phone or pager ring on a set. This is the most common horror for a novice: forgetting to turn the power off his portable phone. It is just about the tackiest thing a producer can do. The crew looks to the sky.
