Joaquin Phoenix / Joker (2019)
2013's Walk the Line actor Joaquin Phoenix took on the role of Batman's infamous super villain in the 2019 film that's quite different from its predecessors, as it serves as the origin story of the killer clown.
Titled Joker, the plot chronicles the evolution of outcast Arthur Fleck and his slow descent into a mad murderer — transforming into the criminal mastermind known as the Joker.
It's no surprise Phoenix took home a variety of awards (including the 2020 Best Actor Oscar) for his portrayal of the character due to the work he put in to prepare.
Similar to Jared Leto's Joker approach, Phoenix transformed physically and mentally with his method madness — losing 52 pounds for the role!
"It turns out, that affects your psychology. You start to go mad when you lose that amount of weight in that amount of time," the actor said at the Venice Film Festival.

Jared Leto / Suicide Squad (2016)
In 2016, Academy Award-winning actor Jared Leto, 46, took a stab at DC's esteemed supervillain, the first major onscreen debut since Heath Ledger's performance in 2008's The Dark Knight — an act critics agreed was tough to follow.
Despite its overall negative reception, Suicide Squad (2016), starring actors like Will Smith, Margot Robbie, and Viola Davis, defied its reviews to become a box office smash.
According to MTV News, the actor's commitment to the part pervaded his off-screen behavior, "gifting" the cast and crew a plethora of vulgar items like used condoms, a dead pig, or a live rat.

Cesar Romero / The Batman Series (1966)
The original Joker, Cesar Romero, was known for his acting and singing skills well before playing the iconic character in the first of the caped vigilante films, Batman: The Movie (1966).
Adam West, the actor playing Batman, said that Romero "brought an enormous amount of energy to the role," in the A&E documentary series Biography, adding, "I don't know how he did it." Romero, however, found the performance relatively easy: "When [you] get in an outfit like that...you fall right into it," he said in the same special.
