Elmore Leonard has inspired some great movies, including Get Shorty and Out of Sight. Also Jackie Brown, which I haven't seen but which my son insists is the best Tarantino movie -- better than Once Upon a Time in Hollywood, he says, if such a thing is possible.
And one of my all-time favorite TV series is based on Elmore Leonard: Justified, about a U.S. marshal in Harlan County, KY, a real place known for coal mines and crime.
I haven't read any Elmore Leonard, but I've heard he's good. The movies and TV based on his work mix suspense with laid-back humor.
