At yesterday's San Diego Comic-Con Breaking Bad panel, Bryan Cranston shocked fans when he revealed that the man who was walking around the convention center wearing a lifelike Walter White mask was actually Walter White.
That is to say, it was actually Cranston cosplaying as his own character.
The actor went on to say that he had been chatting up unsuspecting fans while disguising his voice "in a higher register."
Cranston's co-star Aaron Paul noted that Cranston was "the most professional person I’ve ever worked with but also the most immature man I’ve ever experienced, as you can tell. Which is a beautiful combination."
