Can you match the line to the 2010 movie?

It is a Hollywood truism that writers seldom get enough credit for their work. Sure, they have their guild awards and their own categories at the Oscars, but consider how often you can name the lead actor in a movie or even its director. And the writer? That’s usually a giant leap down the memory scale. Yet we quote lines from movies to our friends incessantly — “I’ll be back,� “There’s no crying in baseball,� “I drink your milkshake!� — those didn’t come from the actor or director. So, in a small nod to all the hard-working but overlooked screenplay scribes, here’s a quiz about some of the memorable lines from this year’s crop of best picture nominees. Match the lines to the film they came from. Hint, there are two per movie.
