Fear And Loathing In Las Vegas movie-maker Gilliam wanted Matt Damon's character, WILL GRIMM, to sport a huge appendage - similar to the false nose Nicole Kidman wore in Miramax movie THE HOURS - but Weinstein objected.
A film insider reveals, "Terry had the make-up artist do tests and finally came up with exactly what he wanted - a large false nose for Damon.
"Terry sent the tapes of the make-up tests to Harvey and received the all clear for shooting but Harvey didn't see the tapes until the day before shooting began.
"He then immediately called up Gilliam, wanting him to drop the prosthetics.
"He claimed he had paid to have Matt Damon as his star so he wanted to see all of his face on the screen, the last thing he wanted was for him to be unrecognisable."
