Shelly Goldstein noticed an unfortunate line in that article I just linked to about The Princess Bride…
6. The actor who played the Albino (Mel Smith) has never watched his performance in the film. This is because during filming, he had to wear contact lenses and was allergic to the lens solution, equating to constant pain while shooting. Hence, he has been reluctant to relieve the uncomfortable memory.
As Shelly points out, there's a good reason Mel Smith isn't talking much about his role in the film. Mel died last July. A great guy, Shelly says.
