Parent Trap, The (Original Version) - The Eyes Have It!
Hmmmm...At the very end of the scene where the big dance happens (at the beginning of the movie), Take a look right after the fight and just as the scene begins to change - One 'twin' has brown eyes, the other has blue, and they are supposedly played by the same person, who is playing identical twins!
Yes, but they probably did that to make it look like two people, different people, to make it look like real twins. twins don't have the same eye colour, They probably put either drops or contact lenses in her eyes to do that.
Hope it cleared that up for you.
