On the ABC airing of this cartoon, the following parts were cut: Most of the beginning (specifically the parts over the opening credits; this was standard practice on ABC). The part where Bugs rings the castle bell by pulling on a noose. Count Bloodcount's line, "No, it's never too late" was cut. The sequence where Count Bloodcount escorts Bugs through the castle had Bugs' comments on all the ghostly objects (including Bugs' line that the castle would be "a wonderful place for a vacation") muted.
Great later period (1963) Bugs Bunny cartoon. I've always found it funny even though some experts consider it not among his best. But then again, what do the experts know?
