Paul Bettany plays the Vision in the Marvel Universe.
Vision is the android Avenger who looks and acts like a man.
But, he's formed a romantic relationship with Scarlet Witch, played by Elizabeth Olsen.
There’s been plenty of speculation among fans about how anatomically correct Vision is.
Without giving too much away Bettany said Vision can change his own destiny.
He can change his density, you know, so with a little imagination that should answer your question.
