This is Part 4 in a series written by Dr. Karen Hayter, one of my favorite TV interviewers (used with permission).

Don’t smoke, or chew gum, tobacco, etc.

Call people by name if you are introduced to them… or take initiative to introduce yourself. Shake hands (firmly) with the people you meet, look them in the eyes, and repeat their name.

Be cordial, kind.

Feel free to use hand motions, facial expressions, whatever you think appropriate.

Be yourself. Don’t fake it and try to be someone you are not; it will come across on camera.

Try to get a good night’s sleep the night before. Don’t fill up on heavy food or sweets or caffeine the night before, the day of, or in the Green Room prior to the program.

If your throat gets dry, try water (at room temperature or a little warmer). Do not drink anything COLD.

Bring a lozenge to suck on for a few minutes. Be sure and bring a tissue to put the lozenge in if you sit down on the set and the lozenge is still in your mouth.

Don’t sniff, or make smacking or other noises with your mouth while on camera.

If you have to sneeze or cough while on camera, try to cover your mic with your hand and turn your head away.

Keep your cool. If you blow it, laugh at yourself. Avoid saying, “uh,” “duh,” “you know,” and other fillers.

Avoid the tendency to say, “In my book…”

Have passion about your subject. Be animated. Have “high energy” but not “over the top.”
