The stars of hit TV show Downton Abbey are grateful they wear elaborate costumes for the period drama as it reduces the chance of fans mobbing them in public. The show has become a huge draw in the U.K. and U.S. since its launch in 2010, and has made household names of actors including Hugh Bonneville, Michelle Dockery, and Laura Carmichael. The stars feared their newfound fame would lead to hysterical fans constantly approaching them on the streets - but their over-the-top traditional outfits mean then can usually go incognito when out and about. Carmichael tells U.K. TV show This Morning, "It's weird. I do feel like we are in a bit of a disguise in period costumes. But yeah, (the public reaction) is mad, particularly in the States. It's crazy."
