Actor Robert Pattinson, who will portray the titular superhero in upcoming film 'The Batman', has said that he tried to do something "radically different" with his Bat-Voice. "Everyone does this...gruff, gravelly thing, and I'm like, 'I'm going to...go really whispery'," the actor said. Robert added that it looked "absolutely atrocious" and was told to stop doing it after two weeks.
