Here is something interesting. Apparently the final installment in the Star Wars franchise, "Revenge of the Sith" (due for release in May, I believe) was rendered on the beta version of the 64 bit version of Windows XP. The Inquirer has reported as follows:
MICROSOFT said that the famous upcoming Star Wars Episode III, Revenge of the sith was rendered on beta version in Windows 64 bit.
This means this operating system is a desirable option if even in its
beta stage it was good enough to render a state of the art movie. The
company called Jak Movies decided to go for Windows 64 bit since it was
faster to render under 64 bit Windows.
