In Shrek 2, during the scene where the king is walking from the balcony, there is a painting on the wall, that some have suggested is Link riding Epona.
I took the Blu ray image from Seriously and did some editing modifications(brightening up what we couldn't see). Its just a painting of a possible young version of the king. So to be clear. Its NOT Link.
I didn't rely on idmb for the info, just a url. When I watched it in theaters, I really thought it was Link, with all their Easter eggs, references, etc. I don't think they had blu-ray in mind at the time, either.
IMDB can't be reliable all the time. I had to look elsewhere for this info. Not a whole lot came up in the search result. So yeah. Case closed on this thread then.
