I can't remember a title for a movie I watched in Australia years ago that I want to see again: it was a comedy about a family who was being forced by the government to move to a different neighborhood - the father referred to his oldest son as an 'ideas man', and they had a vacation home on a lake under some power lines. I remember a lot of scenes vividly, but can't think of the title - does anyone recognize it?
