recently spoke to LEGO Batman
director Chris McKay.
He discussed how Rowling was a pleasure to work with and how they remained true to Voldemort during his LEGO transformation:
J.K. Rowling obviously cares very deeply about these characters, so we absolutely had to run stuff by her. But honestly, there were no notes. The only thing that she gave us was, like, spell suggestions and things like that that Voldemort should say. It was all really positive and helpful. It was never ‘I’m uncomfortable with that.’ I can’t say enough good things about working with her.
At one point I approached the studio and asked if I could get Ralph to do both (Alfred and Voldemort). But unless you’re going to do a scene where Alfred and Voldemort confront each other, I didn’t want something to feel like a missed opportunity. (Laughs.) I do remember when I was pitching (Fiennes) the movie, I said, ‘Yeah, then all of these bad guys are going to be unleashed like King Kong and Sauron and Voldemort—’ And then I stopped for a second because I realized who[m> I was talking to.
