#3 Revolutionary Road
A tender period-piece drama starring the star-crossed lovers of the Titanic themselves, Leonardo DiCaprio and Kate Winslet? Revolutionary Road seemed like it was made to clean up at the Oscars. And while the acting was great - both leads were nominated by several groups - it was only nominated for three Oscars, and the only acting nomination it got was for the perpetually underrated Michael Shannon. Now, part of the reason for this was likely that the film itself wasn't the greatest, but great performances can transcend mediocre filmmaking. Revolutionary Road didn't take home any Oscar gold, but DiCaprio easily could've been nominated and won.
