Shatterglass Films and Chaz Ebert are developing an Emmett Till movie based on the book “Death of Innocence: The Story of the Hate Crime That Changed America.”

The book was co-written by Till’s mother, the late Mamie Till-Mobley, and journalist Christopher Benson.

Till was 14 and visiting relatives in the Mississippi Delta when he was lynched after reportedly whistling at a white woman in 1955. Till’s murder galvanized the Civil Rights Movement.
