The purpose of this thesis is to evaluate and refute Yvonne Griggs’ claims that the films “House of Strangers”(1949) and “Broken Lance”(1954) are as Griggs deems “genre-based adaptations” of William Shakespeare’s “King Lear.”I argue that the films, although they have some essential elements of “King Lear,”lack intentionality and reception, pivotal components in determining viability as a Shakespearean film adaptation. Using Griggs’ book as my critical background, I will show that these films are better classified under their respective genre categories, Western and film noir, not as “King Lear”genre adaptations. I will also suggest criteria for determining the level of canonicity of a “King Lear”film adaptation. Popularity of films does not determine validity, and a film does not need purported Shakespearean provenance to validate its ratings. Some films, like these, merely reference or pay homage to Shakespeare through use of essential elements of “King Lear”; here, I deem such affinities to be more unintentional than intentional.
