Robert Pattinson has played numerous roles, including a vampire, a lighthouse keeper, and many more. Whenever he's set to play a new character for a movie, the actor makes sure to internalize and do his best. However, his latest move for a superhero movie was a different experience.

Appearing in an interview on "Jimmy Kimmel Live!" the "Twilight" actor revealed he originally wanted his voice to be "radically" different from any other Batman actors as their voice sounds low and raspy.

The actor wanted to stand out from the other people who portrayed the role, saying he wanted to do the "exact opposite." (watch the interview below)

The moment he got the role, Pattinson went a different direction and spoke his voice in a "whispery" way. It only lasted two weeks until the production told him to stop doing it.

"I'm gonna go really whispery, and I tried to do it for the first two weeks, and it just looked absolutely atrocious, and they told me to stop doing it," the actor said. (via The Hollywood Reporter)

After the incident, the actor opted to do a deeper and more traditional voice, but he later found out that he wasn't the only actor who took another route.

He told Kimmel that Nick, the man putting him in costume every day, told him former Batman actor Christian Bale did the same for the "Batman Begins" teaser trailer.

He later realized he did the right thing as he felt that it was right, saying, "You can feel when it feels right. You put the suit on, and you have to speak in a certain way."
