Best movie robots in sci-fi

It's impossible to choose between the two most iconic robots in history, so we're cheating slightly and including them both at the top of this list. R2-D2 and C-3PO are loveable individuals in their own right, but their relationship is pivotal to a galaxy far, far away as well as to themselves.

Most people generally favor R2-D2 and it's easy to see why. He's an adorable little astromech droid with a sassy attitude, but also a loyal friend who comes packed with an array of useful tools. No wonder R2-D2 has been immortalized as a highly-detailed Lego set. C-3PO is certainly the most underrated out of the two but he absolutely deserves more praise. 

His panicky outbursts are hilarious, he can see straight through R2-D2's attitude, and C-3PO even saves the day more than once. But most striking is Anthony Daniels' performance that gives the droid an endearing personality. Together or individually, these are the best movie robots of all time.
