How to project a movie on a wall

Select a projector. DVD and hard disk projectors are best for home use. Many projectors play a DVD, including audio. There are also projectors that connect directly to a computer. These systems drive the sound through the computer’s speakers, but separate speakers may be needed for a larger audience.

Find power. Finding the power to run your projector indoors is usually not a problem, but operating an outdoor projector can be a challenge. If you are not lucky enough to find a suitable wall with a nearby power source, you can try running the projector from a car or a marine battery.

Choose a wall that is as white and flat as possible. Colored walls will lend their hue to the image so, for example, a red apple on a blue wall will be purple. A shadow or ripple in the wall will appear through the movie image. You can solve these problems by hanging a white sheet or piece of cloth, with a portable or inflatable screen, or painting the wall with film screen paint.

Position your projector correctly to achieve an image that is as large as possible while still finished. The closer the projector is to the display screen, the clearer the image.

Make sure your speakers are adequate for the size and location of your audience. The sound produced by computer speakers may be sufficient for a small group, but a larger audience may need something louder. The sound from a DVD projector may be sufficient, but you can also use remote speakers, tune in surround sound, or even broadcast audio through a range of FM radios (see mobmove.org).

Tips and warnings

When projecting a movie outdoors, it is wise to talk to your neighbors and get their support for the event. A visit from the police can make a muffler on your movie night.

Most movies are copyrighted. Showing such a film in a private home does not break the law. Showing the same movie anywhere that is not a private residence is against the law if you have not paid for a public performance license, which is quite easy to obtain and relatively inexpensive. More information is available at www.mpaa.org/Public_Performance.asp.

Projecting a film on a wall is in most cases a simple task. Previously, you needed a traditional film projector – complete with film threading, film breakage and an uncooperative sound system. Film projection systems have come a long way since then, especially for the non-professionals. Now it’s easy to create a movie night for you friends and family at home. And with a little more effort, you can host an outdoor event for the entire neighborhood.
