I saw this one a few days ago because folks were posting about it earlier. Great movie! My guess is that despite the current anti-smoking climate, a pipe company wouldn't have the same profit revenue that a candy company or even a bottled water company would have for product placement in such an expensive movie. But, my guess is that it's a Chacom. They make a huge range of "regular" looking pipes. My first thought was that she should have been smoking a more exotic looking pipe, like a churchwarden or Savinelli Clark, but... they wanted to make sure we "the audience" would assume it is normal tobacco and not marijuana. We are sort of sheltered in our thinking, being a part of the pipe community; however, the majority of the population still thinks every mention of "weed" in Tolken's work is a reference to marijuana, just like a pot smoker assumes that every word in an obscure song or piece of literature is obviously a drug reference... to them. For example, Peter Paul and Mary have stated inumerable times that their song, Puff the Magic Dragon, had nothing to do with drugs, but drug users just keep on associating the song with drugs, regardless. So, giving Miss Perigine the most "average" looking pipe possible, without being TOO male looking. A straight pipe, of course, would have looked too masculine and virile. A bent pipe, no one associates a bent pipe with virility. Nothing against them, but a droopy bent was a "safe" choice, IMO.
And, I think Chacom, because I can't think of which shape by Savinelli that it would be, and it just has that "average" look that I associate with Chacoms.
