Yeah. Movies about entertainers and athletes will be a sweet spot for that.
Samuel L. Jackson in Coach Carter. He was born in 1948 and Ken Carter was born in 1959. But nobody really knows who Ken Carter is.
Thought I had one with Moneyball. But Billy Beane is a year older than Brad Pitt.
Quinton Aaron is a few years older than Michael Oher in The Blindside.
Something not related to the sports/entertainment world. Redford and Hoffman were a bit older than Woodward and Bernstein.
