You'll Become An Expert On: Global Warming
Climate change deniers seem about as credible as Birthers these days, but that shouldn't stop you from pontificating to your friends about the dangers of global warming after seeing this movie.

Though there are tons of boring charts, graphs, and proposals you could dig up to further educate yourself regarding global warming, why not just pop in the blu-ray of The Day After Tomorrow and call it additional research?
