Unexplained Super Memory Skills - Bob Petrella - Jill Price - Brad Williams - Rick Baron

A recent article from the Mental Floss Blog shows 4 people who have an
unusual memory ability.
These 4 people are said to have a variation of OCD that allows them
to remember complete details of certain events such as each play of a
particular sports game.
There is a movie/documentary coming out soon about Brad Williams and
his memory skills.
Title of the movie is Unforgettable.
There are probably many others with these unusual memory skills.
