Good Behavior series premiere TV billboards...

If you ever wondered what happened to 'Lady Mary Crawley' after Downton Abbey finished, now's your chance to find out.

Well, not exactly, but Michelle Dockery who played the member of the British aristocracy in the period drama returns to the small screen in her new crime noir drama on TNT, Good Behavior.

Trying to play almost the opposite of her post-Edwardian English character with all its airs and graces (and gowns), she plays 'Letty Raines', the troubled drinking, druggy ex-con trying to go straight in South Carolina.

Like the tagline says, she's 'bad at being good' and after being released from prison she soon falls back on her old con artist tricks, stealing and grifting in disguises, until she meets a sexy hitman, 'Javier' (played by Juan Deigo Botto), and becomes embroiled in his contract killer schemes.

These Good Behavior billboards (with Michelle Dockery behind the show's neon title treatment) were first spied along West Hollywood's Sunset Strip on September 17, then later along La Cienega Boulevard on September 26, 2016.

The follow-up billboards (with the leading lady to the left-hand side of the logo) were snapped along Melrose Avenue and Sunset Boulevard on November 2, plus the 'For your consideration' version was spotted along Pico Boulevard on November 8, 2016.

Will the actress be able to make it on her own with this new self-destructive alias, or will she forever remain Lady Mary in the eyes of viewers after six season of the popular period drama.

If all else fails there's rumblings of a possible Downton Abbey film in the future, so it's not all bad news.

UPDATED: Here's also a series launch billboard for the show captured along Broadway at W 49th St in New York City on November 11, 2016.

Plus another teaser billboard for the new TNT show was snapped down in the Meatpacking District the same day.

UPDATED: In addition to all the standard billboards Michelle Dockery has also been super-sized along the Sunset Strip.

This giant-sized Good Behavior billboard was first spied on the side of West Hollywood's Andaz Hotel on November 14, 2016.

UPDATED: Here's also some examples of the season two billboards for Good Behavior snapped along the Sunset Strip and La Cienega Boulevard from October 4 to October 12, 2017.

From the looks of things Letty doesn't look too happy to be back, but maybe that's because of the gun.
