I think wider-angle lens do create the false impression that the space is bigger -- take a look at Terry Gilliam's "The Fisher King" , there are some scenes in a tiny basement with Robin Williams but shot with a 14mm lens -- it looks more spacious than it probably was to shoot in. I've shot handheld with very wide-angle lenses and have bumped into things because I thought they were farther from the lens than they actually were.
Of course, if you can back the camera through a door or window and get a bit wider, that will help. Some people even get a front-surface mirror and shoot into that to get the camera "inside" the wall so to speak, backed up effectively (but probably at an angle in order to not see the camera in the reflection.)
However, if wide-angle photography is not part of the visual style of the movie, then you're better off changing locations so that you can get a wide shot on a less wide-angle lens. I don't like it when one scene is shot super wide-angle because the room was too small when the rest of the movie does not have that feeling.
