2008's sci-fi remake The Day The Earth Stood Still presented Keanu Reeves with the role he was born to play: An emotionless and monotone alien. Except for the otherworldly part, that's the man to a tee. Even when it's apparent that he's trying his best to emote (Speed, A Walk In The Clouds), Reeves always seems like he's sleepwalking through his films, waking up to deliver variations of "Whoa," before counting more Z's while on his feet.
