Watch Matthew Rhys in the new trailer for HBO’s Perry Mason origin series

Set in 1932 Los Angeles, the series will focus on the origin story of famed defense lawyer Perry Mason, based on characters from Erle Stanley Gardner’s novels.

Living check-to-check as a low-rent private investigator, Mason is haunted by his wartime experiences in France and suffering the effects of a broken marriage. L.A. is booming while the rest of the country recovers from the Great Depression – but a kidnapping gone very wrong leads to Mason exposing a fractured city as he uncovers the truth of the crime.

If there are any people out there looking for inspiration for the look and feel of their Call of Cthulhu RPG campaign then this could be a big help.

The show stars Matthew Rhys, Tatiana Maslany, John Lithgow, Chris Chalk, Shea Whigham, Juliet Rylance, Nate Corddry, Veronica Falcon, Jefferson Mays, Gayle Rankin, Lili Taylor, Andrew Howard, Robert Patrick, and Stephen Root.

It hits HBO on 21st June 2020.
