Joker movie billboards...

Cesar Romero, Jack Nicholson, Heath Ledger and Jared Leto are just some of the actors to play Batman's arch-nemesis, the 'Joker', over the years.

Now it's the turn of Joaquin Phoenix to don the sinister clown makeup as 'Arthur Fleck', a man disregarded by society to their eternal regret.

Director Todd Phillips brings the iconic DC villain, created by Bill Finger, Bob Kane and Jerry Robinson, to the big screen in his own gritty standalone origin story.

These movie billboards capturing the insanity of the Joker were spied along Highland Avenue, 3rd Street, Cahuenga Boulevard and the Sunset Strip from September 21 to September 25, 2019.

For more ad creatives featuring the Joker, be sure to check out these billboards for The Dark Knight, these Batman Arkham City game billboards and these Suicide Squad movie billboards.

The film has already received accolades for Phoenix's portrayal of a mentally ill aspiring stand-up comedian and clown-for-hire, but the movie has also garnered criticism for its depiction of violence, especially from the families of mass shooting victims.

It's interesting that Warner Bros. Studios feel some of DC villains deserve their own standalone movies (with another Suicide Squad movie on the way), when their pantheon of superheroes still haven't all starred on the big screen.

Let's see if this depiction of the Dark Knight's classic foe will make a killing at the box office this October.

UPDATED: WB Studios certainly want you to think of Joker as an awards-worthy movie, and this "The film of the year" ad creative was snapped along Highland Avenue on October 1, 2019.

Plus here's a larger version of this review-laden billboard spotted along the Sunset Strip the following day.

And fans of the movie can also check out Joaquin Phoenix's Joker movie costume on display.

Undone series premiere TV billboards...

In Amazon Prime Video's trippy new adult animated series Undone, Rosa Salazar plays the central character, 'Alma', who survives a near-fatal car accident and starts exploring the elasticity of reality.

With the help of her dead father (played by Bob Odenkirk) she discovers she has the ability to manipulate time, as he teaches her to use her powers in order to help investigate his murder and save his life. But is it really happening, or is it all in her mind?

This series uses rotoscoping, where animators trace over live footage for a smooth by surreal effect, helping to give Undone a sense of unreality.

These eye-catching series launch billboards were photographed along La Brea Avenue and San Vicente Boulevard on September 21, 2019.

Fans of Rosa Salazar can also enjoy these Alita: Battle Angel movie billboards from earlier this year.
