Thomas and Martha Wayne both had brown eyes.

But Bruce Wayne had blue.

hmmm, isn't it very remotely technically possible, according to the good ol' Punit square? They would both have to coincidentally carry the recessive gene, then Brucey coincidentally picked the winning number from both sides...

Yeah, but for some reason it's something that I tend to always look at whenever eye color of family members is given in movies and games.

Oh, and even more rare is the brown-eyed child from blue-eyed parents.

But of course, my absolute favorite is the chimera. :)
