Which McDonald’s menu item gave Captain Crook his name and advertising identity?

The Filet-O-Fish gave Captain Crook his McDonald’s advertising identity.

Captain Crook was a pirate-themed McDonaldland character used to promote the Filet-O-Fish sandwich. His name, costume, and nautical presentation connected him with the fish-based menu item rather than with McDonald’s hamburgers or chicken products.

Captain Crook is sometimes confused with the Hamburglar because both were portrayed as mischievous characters. Their advertised products were different: the Hamburglar pursued hamburgers, while Captain Crook represented the Filet-O-Fish.

The Filet-O-Fish itself was introduced in 1962 after a McDonald’s franchisee developed a meatless sandwich for customers who did not eat meat on Fridays. The character later helped give the product a memorable place in McDonaldland advertising.
