From the trailer I thought...
That this was a true story about a mentally handicapped person that went to the Olympics and did well, being that I've never heard of the story.
But then I googled it a saw that no, he actually got last place in everything he did there. I also watched a few interviews of this guy out of curiosity and he does not seen even nearly as retarded as he did in the trailer.
I get this is an "inspirational" movie about an average person pursuing their dreams in a cool runnings fashion. But why in the movie did they make him look as retarded as he does?
