This is one of the most sought-after "Morlock" collectibles.
After the unexpected success of the original "Professor Morlock," the studio scrambled to cash in on the franchise as quickly as possible. One of the first items they rolled out was this Professor Morlock plastic model from Aurora Hobby Kits. Jesse Merlin immediately tried to sue to keep them from using his likeness without recompense, but the first film contract he signed after rising to fame as a star of the Barstow Opera Company was hopelessly in the studio's favor and he failed to make a dime off the lucrative Morlock licensing gravy train. It resulted in a bitter feud over money that lasted for years.
A mint-in-box "Morlock" Aurora model can fetch up to $5,000 on eBay.
