Last week, we all took notice of Bryan Cranston's time at Comic-Con: the man behind Breaking Bad's meth-making Walter White went around the convention wearing a mask of...well, Walter White. And on David Letterman last night, Cranston talked about what that whole experience was like.
The reasons why he would do this are obvious: he'd get mobbed on the floor if he just went out "normally". But he also mentions how he got the idea to cosplay as Walter White, and how he had to take extra steps to make sure people didn't recognise him — like taking up a Michael Jackson-like voice. Funny and well-played, good sir.
