Playing a Marvel character can be stressful according to Jared Leto, but it sounds like he was up to the task.

Speaking with Variety in support of his upcoming film Little Things, Leto had a lot to say about Morbius. Although the film was recently delayed again due to the pandemic, he shared some thoughts on what it took to take on the role.

“It’s a big, fun movie filled with action,” said Leto. “It’s a brilliant doctor, a researcher, who starts off trying to find a cure for a very rare disease that he has and about 1,000 other people in the world have. I was interested in this role because he goes on this journey from dying to finding a cure for this disease and becoming incredibly healthy, and then having things change in a way that he becomes monstrous. So, it’s a bit of a Jekyll and Hyde, which is of course a classic role.”

“It’s a pressure cooker,” Leto shared. “You have a clock ticking. They’re expensive films. And so, all of the decisions and the time to make those decision are a little bit more heated and so it can be a little more stressful. I think it’s more common with these big movies, you don’t really start with a gem of a script.”

“You start with a hope and a dream and an idea of something,” Leto continued. “And you all try to work as hard as you can, in this given amount of time, to make it as good as it can be. And I think it’s the first time I’ve ever starred in a big movie like this in my entire career, so it was new territory. I generally hide out in the shadows.”

Morbius is set to hit theaters on Jan. 22, 2022.
