Spot The Difference?
Bret McKenzie was in Lord of the Rings! Probably not surprising, since at one point approximately 87.8% of the population of the entire country was employed, in some fashion, by making that movie.
He appears very briefly in Fellowship (I had to zoom in to notice it was him), and then again very briefly in Return, where his character says 7 words. And yet, he has fansites. The internet is truly an amazing place.
