If you prefer the real thing over the blow-up version, here's an outdoor movie screen that's just as portable as an inflatable model, but made of a 16:9 Oxford nylon screen. Project 120 inches worth of movies indoors or out, no pump needed. I recommend anything with Ben Stiller.
Just kidding. I recommend nothing with Ben Stiller.
Camp Chef's movie screen frame is made of 1-1/2" diameter steel tubing, with legs that stake into the ground. A set of four guy ropes and their stakes are included for additional stability. A pair of storage bags for both the screen and the collapsible frame also come with the set.
