Wooosh, that should change. You couldn't have a worse case setup unless you painted the walls and ceiling with reflective projector paint. I'm sure everyone in here would suggest at least going a couple shades darker with a flat/eggshell finish. If you're doing that you may want to think of the darkest wall color you'd be comfortable with.
All the lumens coming off that projector are getting reflected off the screen to produce the image. In your case it would probably light up the whole room like a disco light. When looking at a room with a front projection theater I think of it kinda like sound, but with colors. You want colors and textures that suck up the lumens, not reflect them. The light bouncing off the screen will bounce off everything to some degree, and glossy stuff seems to almost double the reflections going on (at least when I've seen glossy painted walls).
