* Farce is a type of comedy characterized by absurd situations, slapstick humor, exaggerated characters, and rapid-fire dialogue.
* Sonnet is a specific type of poem with a strict structure and rhyme scheme, not applicable to film genres.
* Fantasy involves magical elements and settings, not a primary focus of Austin Powers.
While Austin Powers has elements of satire and parody, the core of its humor lies in its over-the-top silliness, ridiculous characters, and physical comedy, which are all hallmarks of farce.
