Kelly Macdonald says she watched The Penguin to prep for Lanterns, and picked up the wrong accent along the way.
"Within the first couple of months of the shoot, as well, I was watching The Penguin at the same time," Macdonald told Entertainment Weekly. "Sometimes I’d been over-watching The Penguin, and I’d be going through my dialogue in my trailer, and I'd realize I was doing the whole Gotham thing. I’d be like, 'Turn it down a little bit,' 'cause I’d been told very specifically, 'She's from Gotham but don’t do the accent thing.' She has to be more ambiguous than that. I’m sure you’ll be able to tell the scenes where I’ve been watching The Penguin."
