"A toast to my big brother George: The richest man in town." So ends It's a Wonderful Life, probably the most well-known film with a communitarian climax, where the lead character George, both finds meaning for himself through his sacrifices to others, and sees it come back to him as family, friends and respect in the community bring him real wealth, literal and figurative.
Katniss Everdeen is no solitary heroine. The theme that through mutual help and cooperation with others, we can achieve more than we could on our own also pervades the popular book and film series the Hunger Games. We see this through the decision of Gale and Katniss not to run away from the District in the beginning, Katniss volunteering to take the place of her sister Prim as a tribute, the critical help given to Peeta and Katniss by Haymitch their mentor, Cinna the stylist, the help Peeta and Katniss give to each other, the strategy of forming teams within the game including between Katniss and Rue, and through the gifts, which depend on the ability of the tributes to win sponsors. Finally we see it in the finale, where the power of selflessness allows Katniss and Peeta to break the rules and escape the games.
