Matt Smith Was Bart Simpson At Comic-Con And Nobody Knew (VIDEO)

BBC America

"Doctor Who" star Matt Smith posed as Bart Simpson at Comic-Con in San Diego this weekend and nobody knew. Yes, SDCC goers: You may have met the Doctor and had no idea.

Smith donned a Bart Simpson mask and did his best American accent while walking around the convention floor and BBC America documented the excursion. He complimented "Doctor Who" fans wearing items of clothing from the BBC hit and even posed next to a photo of himself.

Smith wasn't the only TV star to put on a costume at Comic-Con this year. Bryan Cranston walked out on stage for the "Breaking Bad" panel wearing a Walter White mask that he walked the floor in as well. Check it out below.
