I don't agree with asadullah.ansari's answer.
How do you define old ?? Peter Pan is of 1953. It is old enough too.
Another point :
If I say choose the odd one out between You, Your Mother, and Your Grandpa; would answer me "Grandpa" because he is oldest ??
No, the answer should be Mother as she is female. (assuming you are male)
So, my point is old one does need to be the old one out.
I think the answer will be PETER PAN
because all others are animated.
