And, let's not forget quite possibly Herbert Marshall's greatest role, that of the skeptical Montreal police inspector, who, cannot believe that Vincent Price's sister-in-law killed his own brother (actor David Hedison of "Voyage to the Bottom of the Sea" fame ), because his brother had accidentally (not to mention allegedly) transformed into a six-foot half-man, half-fly monster during an ill-fated experiment in the cinematic sci-fi classic, "The Fly."
Who could possibly forget that final, chilling scene in which Herbert Marshall (along with Vincent Price) is looking down at a tiny fly with David Hedison's head on it, caught in a spider's web and about to be ingested by a hungry spider, and pleading in a very squeaky voice, "Help me! Help me!!"? (Of course, Mr. Marshall's character did the only proper thing and squished both the fly and the spider with a heavy rock.)
