You know, I was thinking about this while I walked over to a meeting...what the hell is Ford talking about?
They always used a professional whipmaster as a double for anything more complicated than a basic swing anyway on the other Indy flicks. All Harrison ever worked with were the "hero" props...the pretty whips that coiled nicely on his belt. Nothing's changed...he'll still have a practical prop for all his scenes, and instead of a double coming on to do the more rigorous whipping, they'll cg it in.
Of course, I'm skeptical about a CG whip in terms of how it will look and would rather they stick to a practical prop myself, but we all know that Lucas will CG Indy's hat into every shot if he wants to.
Retard.
