There’s no real point in doing a test screening just to hear the viewers mumble to themselves on the way out the door. Make a questionnaire with specific questions. “Did you like this?” might be what you really want to know, but the answers you get won’t be incredibly helpful. If you’re lucky enough to have multiple test viewings, divide your audiences up based on their relationship to the project. Are they friends and family? Are they industry professionals who read the script? Are they drunken frat boys who thought there would be free booze and strippers? You’ll want to keep all these in mind when evaluating the responses. Sometimes you can even tailor your test audience to the material. If your project is about a narcotics detective busting up a drug ring, have a test screening for cops. Or if your social network skews in the other direction, have a screening for drug dealers (and maybe the cops will show up). While there are some obvious biases in these types of test audiences, you’ll also get the benefit of lived experience.
