"When You Believe" gets its first airplay on October 7, but if you want a preview of about 3 lines of the main chorus (sung mainly by singers other than WH or MC) the trailer can be downloaded at http://www.theatres.sre.sony.com/trailerpark/trailers/0188xx.mov.

WYB pops up towards the end of the trailer. The trailer does take about an hour to download. The very last second of the trailer switches from the Dreamworks chorus to what sounds like the WH/MC single, although the voice in my opinion sounded more like MC than WH. A very high pitched voice sings "...when you believe." and then it fades into a glimpse of the Babyface background.
