An actor demo reel (also known as a showreel  or sizzle reel ) is a one- to two-minute-long edited video collection of an actor's best performances. Talent agents, managers, casting directors, and potential employers view demo reels when searching for new acting talent.
Each clip should be between 20-30 seconds long, and the entire demo reel should be two to three minutes long, maximum. Your reel should also include your name, contact information, headshot, and website.
