Strange noises in "The Wicker Man" trailer?
I've never seen the movie and a trailer for The Wicker Man on DVD TV. Towards the end of the caravan, there was a very strange noise that sounds almost like a drunk frog saying again and again. My BF and I were like "wtf". Does anyone whose seen the movie knows what is noise? We've seen the trailer like five times and has been increasing, so obviously there was nothing wrong with the TV.
Haha thats Hafta kinda funny im gunna check this!
