In looking up the topic of people with the different eye colors, i found that people with the condition (which sounds like a bad thing, but it isn't) can also have say, a blue eye with brown rings around it or an eye that is partly blue and partly brown, like that, as well as other colors.
Some notable names with the one eye one color and one eye another are: Mila Kunis, Dan Aykroyd, Jane Seymour, Kate Bosworth, Henry Cavill, Alexander the Great, Gracie Allen and Wentworth Miller, to name a few.
See this link and see a total of 39 on the list, including the ones I mentioned, with variously different eye-colors connected to this condition. Seriously did not know this about most of them! Because it's the "Sports Thread", I'll add that there's one other MLB player, on the Phillies, whom I don't really know.
