X2: X-Men United (2003)

The film's central thesis explicitly promotes progressive ideology by using mutants as an allegory for marginalized groups fighting against systemic discrimination, government-sanctioned oppression, and the fear of the 'other,' championing peaceful coexistence and civil rights.

The movie presents visible diversity within its ensemble cast, though it does not explicitly recast traditionally white roles with minority actors. Its narrative, however, strongly critiques traditional power structures and societal prejudice through its antagonist, making the themes of marginalization and the fight for acceptance central to the story.
