Having recently seen the first trilogy among Nolan’s works, I wonder what opinions you hold about the movies in general. Seeing that I’m quite late to the party, I expect some strong and mature takes in the comments, but you are still free to voice any opinion you may have.
Richard Harris did a similar thing in Cromwell (1970). Though he did the voice by actually breaking his voice. Bale probably broke his voice for putting the voice on lol.
Anyway, Harris’ voice was excellent in Cromwell. Bale’s voice was silly in Batman.
