It's nearly time for "Perry Mason" to hit the streets of Los Angeles once again.

HBO's limited series revival of the classic Perry Mason TV series premieres on Sunday, June 21.

Back in April, we saw a brief teaser trailer that offered little more than a sense of the show's atmosphere. But today, HBO debuted Perry Mason's official trailer, which gives a two-and-a-half minute preview of the upcoming show.

The trailer is captioned: "Everyone is guilty of something." Check out Matthew Rhys as "Perry Mason" below!

HBO provides this official description for the series, which appears to be a grittier new take on the classic TV show:

"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."

Robert Downey Jr. was originally pencilled in to star in HBO's new adaptation, but he later shifted to an executive producer role. Tatiana Maslany, John Lithgow, Chris Chalk, Juliet Rylance, and Shea Whigham round out the cast along with leading man Matthew Rhys.

Perry Mason returns to TV in June 2020

Raymond Burr originally starred as the attorney between 1957 and 1966 on TV's Perry Mason, as well as in a series of films in the 1980s and 90s.

Emmy-winner Matthew Rhys takes on the role this time around, seemingly as a more noir-inspired detective version of "Mason." Rhys is best-known for his role on FX's The Americans.
