While the rest of the Avengers try to choose sides in "Captain America: Civil War," the newest member of the team will be dealing with a much more philosophical challenge: Understanding the complicated nature of love and loyalty.
"I think he’s very interested in what it means to be human and what love is," Bettany explained. "The only way one can guarantee one’s loyalty is love. Loyalty is beyond logic, really. Logic doesn’t really provide for loyalty. If your logic changes suddenly and things not make sense, you can alter your allegiance, but love stops you from being able to do that."
In other words, Vision will face the same issue that has been confounding androids onscreen since forever -- the collision of clean, cold artificial intelligence with sloppy human emotions. Below, we've rounded up some of the other 'droids who were confounded by love.
Sonny, "I Robot"20th Century Fox
Sonny could never entirely understand human relationships, but he still craved connection and understanding a lot like a person would.
Wall-E learned about love and heartbreak at the same time, thanks to a unrequited crush on another robot.
David, "AI"Warner Bros.
This pint-sized android was so expertly designed to mimic the emotions of a dependent child, he fooled everyone, including himself.
Johnny 5, "Short Circuit"
