In 1967, after having the DePatie-Freleng production team make their cartoons for the last 4 years, the Warner Bros. cartoon studio reopened though instead of bringing back their classic characters-other then Daffy Duck and Speedy Gonzalas-they created new ones. This one marked the debut of the title character with the W.C. Fields-like voice which is impersonated here by Daws Butler, not Larry Storch like subsequent ones. Butler also voices Second Banana and a cat. Anyway, the theater that Merlin and S.B. are playing has just that cat in the audience so the magician puts on a big mustache to disguise himself. Okay, that's pretty lame but it fools the cat for awhile. Now, other than a wheel with gloved hands on each spoke making "appaluse" sounds, there isn't anything even amusing in this short. The whole thing has the feel of really lame Hanna-Barbera TV cartoon product which was the quality of the actual thing at this time which shouldn't be surprising since one of that company's directors, Alex Lovy, helmed this one. So on that note, Merlin the Magic Mouse is definitely not recommended.
