There's a great video up on the tubes from the Warner Archive including a pie count

Here's a HQ without a pie count

I recently found a behind the scenes video on the great race. I'm especially stoked that the parts of the movie leading up to the pie fight have actually been filmed in Austria, pretty close to where I live and produce myself Sadly the behind the scenes look does leave out the pie fight itself. I would assume that that part would have been shot in a controllable studio set but perhaps someone has more info on that.

Warner Brothers picked up the picture from United Artists due to escalating costs.

Indoor scenes were shot at WB, Burbank, California on various sound stages.

Epic fun!

Thanks Richard for this and WAM Photography for the HQ version.

I seem to recall there's an earlier scene where Natalie Wood bathes in a pond in her underwear.
