We like to have a "Movie Night" from time to time. For this, the kids love it when I set up the video projector outside at night and project on the side of the RV. Feels like a drive in :) We usually invite the neighbors and others we meet. We've been doing this at least 10 years, and I'm always surprised how receptive folks are to it. We've never had a complaint, and we've met lots of nice people this way. We're just always careful of not abusing the volume knob.
