Doppelganger Fail?

Spencer and I were shopping in a local sporting goods store tonight and one of the guys who worked there asked me if I had ever seen the movie "Prefontaine"-- of course I didn't even know what a Pre Fond Tang was...
He told me that my son looked just like the star of the movie--and if Spence were older--AND HAD A MUSTACHE-- it could be his twin.

Very odd indeed.

So I googled the movie.  It's about an olympic hopeful runner who dies.
I don't see where the resemblence to my son is so striking that a complete stranger would walk up and comment on it... But on a related note, Spencer is much cuter without facial hair.
