It was Sir Laurence Olivier who slyly critiqued Dustin Hoffman's method technique during the Marathon Man shoot, advising him, "Try acting, dear boy". Maybe this was Olivier making a witticism at Hoffman's expense but in the case of Jared Leto, it could be the central sentiment in his intervention. In playing the DC Comics villain, Leto has gone method in the most obnoxious way.
So lock your doors and get a restraining order, because these are the most annoying things Jared Leto has done as the Joker.
Delivered a Dead Pig During Rehearsal
The Method: Interrupting a rehearsal with a videotaped message and a dead pig.
The Madness: Much like the Joker would do (really?), Leto used production assistants on set to send dead farm animals to the nice men and women of the Suicide Squad (who are just playing bad guys)
But Maybe: Actually, several the actors said that this kind of worked and really united the cast in an "us against him" sort of way. If this shows in the final product, Leto's approach will have paid off.
"Joker" Mailed Margot Robbie a Live Rat
The Method: Leto had a rat delivered to Harley Quinn actress Margot Robbie.
The Madness: Any fan knows that the Joker and Harley's relationship is messed up, but does any actress deserve to have her more highly paid mail co-stars sending her rodents?
But Maybe: These two characters are twisted, with Quinn torn between abject worship and justified disgust. Opening a package with rat inside might just help convey the gruesome, contradictory push and pull between Mr. J and Miss Q.
Used Condoms and Anal Beads for Everyone!
The Method: Mailed used condoms and anal beads to the actors playing the Suicide Squad.
The Madness: Did you not read that first line?! What the hell does this have to do with the Joker?
But Maybe: When asked, Leto said, "I did a lot of things to create a dynamic to create an element of surprise, a spontaneity and to really break down any kind of walls that may be there," - you know, things established by Human Resources to avoid sexual harassment and the spread of disease.
Adewale Akinnuoye-Agbaje Got "Sticky" Playboys from Leto
The Method: Sent mysteriously sticky copies of Playboy to Killer Croc actor Adewale Akinnuoye-Agbaje.
The Madness: It's to be inferred here that the Joker "took himself to dinner" while perusing the contents of Hugh Hefner's publication... and then sent it to an actual person who isn't really a DC villain.
But Maybe: Maybe Killer Croc gets his hands on Joker and reenacts that scene from Fight Club when Edward Norton wants to destroy something pretty.
