It's not a secret that Jared Leto was very serious in portraying his role as Joker in "Suicide Squad."

But weeks after "Suicide Squad" wrapped up, there are rumors that Jared Leto could still be channeling his Joker personality.

"The 43-year-old star looked twice as nice as he went for a stroll in New York City's SoHo neighbourhood on Thursday," Daily Mail reported.

"Jared's brightly patterned harem trousers and colour-slashed poncho went well with his slicked back hair, which he died pink not long after wrapping up his role as The Joker in the superhero flick Suicide Squad six weeks ago."

"The star is known for his Method acting style, in which he stays inside the mind of the character he's playing even away from the camera," the report continued.

Even Jared Leto's "Suicide Squad" co-stars have noticed the actor's dedication to his Joker role. Will Smith recently raved about the "Requiem For A Dream" star's performance.

"I've never actually met Jared Leto," Will Smith reportedly told Zane Lowe on Beats Radio 1, as quoted by New York Daily News.

"We worked together for six months and we've never exchanged a word outside of 'Action!' and 'Cut!' I literally have not met him yet. So, the first time I see him will be 'Hey, Jared. What's up?' He was all-in on the Joker."

Jai Courtney, who plays Captain Boomerang in "Suicide Squad," also previously dished out to MTV about how dedicated Jared Leto was to his role as The Joker.

"I don't think any of us are naïve to the pressure he's under," Courtney said. "It's not something I've talked about with him, but I've seen him working and it's cool, man."

When asked if Jared Leto has gone method acting for his "Suicide Squad" role, Jai Courtney was quite unsure of the answer.

"Sort of," Courtney said. "I don't know how you measure that these days. I haven't seen him, since we started working, out-of-character, let's put it that way."
