It has been 25 years since Perry Mason, arguably the most famous fictional lawyer of all time, has graced the screen but now HBO is about to introduce him to a new generation. The new series is called simply Perry Mason and it stars Matthew Rhys (The Americans) in what is being described as an origin story for the legendary criminal defense attorney. This is not a contemporary update but rather a period piece set in 1932 Los Angeles, a city that is booming while most of America is still recovering from the Great Depression. The plot revolves around a child kidnapping gone wrong and it is executive produced by Robert Downey, Jr. (who was originally considering playing Mason himself at one point). Directed by Tim Van Patten (The Sopranos, Boardwalk Empire) and written by Rolin Jones and Ron Fitzgerald (Weeds, Friday Night Lights), the show also stars Tatiana Maslany, John Lithgow, Chris Chalk, Shea Whigham and Juliet Rylance. Perry Mason premieres on June 21st; check out the first trailer below and see what you think.
