Gene Kelly’s character, like Errol Flynn’s Robin Hood, is the blueprint followed by the leading men in The Princess Bride, The Pirates of the Caribbean, and Tangled. Gene Kelly’s character in DuBarry Was a Lady a similar character reminiscent of Robin Hood. 

Lord Farquaad is inspired by Prince Humperdinck.

Both films are fairytale deconstructions inspired by Tristan & Isolde, which also inspired Vertigo and Mulan/Aurora’s romance in Once Upon a Time.
