The sci-fi adventure series Doctor Who has been a fan favorite for more than 40 years. The original run of the show, from 1963 to 1989, is mostly remembered by Americans for its cheesy special effects and distinctly British eccentricity. A series revamp in 2005 dispensed with the former and kept the latter - it's a huge hit, both critically and commercially, in the UK.
This month the fifth series of the new version of the show launched on BBC America, with a new head writer (the highly acclaimed Steven Moffat), a new Doctor (Matt Smith) and a new companion (Karen Gillan). Moffat, Smith and Gillan are our guests on this Sound of Young America. They talk bout the significance that Doctor Who held in their lives, and about what it's like to put a personal stamp on a revered cultural phenomenon.
