"Look, I bring forth my work to this job, and I do the best that I can," he said when asked in the interview if he had any issues co-starring with Depp in wake of Amber Heard's domestic abuse allegations against the movie star.
"I would say that literally every single aspect of my reality, inclusive of a lot of things that are not fine with me, are fine with me," he continued. "It's amazing how far the banner of all good can extend."
Rowling was all good with her decision to cast Depp as the eponymous villain in the film even after fans made a stink on social media in December of 2017.
"Based on our understanding of the circumstances, the filmmakers and I are not only comfortable sticking with our original casting, but genuinely happy to have Johnny playing a major character in the movies," she said at the time.
"I accept that there will be those who are not satisfied with our choice of actor in the title role," she added. "However, conscience isn't governable by committee. Within the fictional world and outside it, we all have to do what we believe to be the right thing."
Depp has been maintaining in recent interviews that he was "falsely accused" of abusing Heard, and said in October that Rowling has seen the evidence backing up his side of the story.
"The fact remains I was falsely accused, which is why I'm suing the Sun newspaper for defamation for repeating false accusations," he told Entertainment Weekly. "J.K. has seen the evidence and therefore knows I was falsely accused, and that's why she has publicly supported me. She doesn't take things lightly. She would not stand up if she didn't know the truth. So that's really it."
Miller also addressed another casting controversy that caused a stir from fans on social media. Is Henry Cavill really done playing Clark Kent and Superman in the DC Extended Universe?!
After fans started railing on Warner Bros. for reportedly parting ways with the actor, his manager released a statement suggesting the story wasn't very reliable. "Be peaceful, the cape is still in his closet. [Warner Bros. Pictures] has been and continues to be our partners as they evolve the DC Universe."
WB simply said, "While no decisions have been made regarding any upcoming Superman films, we've always had great respect for and a great relationship with Henry Cavill, and that remains unchanged."
In any case, Miller said fans can at least "trust" that his upcoming DC solo movie as The Flash, a character he began playing in "Batman v Superman," is on the way.
"Nothing is ever certain in this world, but as certain as things get, we're making a f--king crazy-dope Flash movie," he promised. "It's one of my great life dreams, and just the fact that we're on the way -— anyone who knows about Barry Allen knows he may arrive late, very late, but once he gets there, it's all solved. We have to trust."
