Some people whose lives and work leave an inheritance of for more than just their families. If you go to the movies this weekend, you may witness part of Martin Luther King Jr.’s legacy in the movie Selma, which goes into wide release this weekend. But it’s only part. David Garrow wrote the King biography “Bearing the Cross: Martin Luther King, Jr., and the Southern Christian Leadership Conference”, which won a Pulitzer prize.

Lizzie O’Leary speaks to Garrow about the version of Dr. King that moviegoers will see in Selma, and what part of his legacy is public.
