Tom Baker has played some of the juiciest roles in all of film and television. He began his career on the stage as part of Laurence Olivier’s National Theatre company in the late 1960s and early 1970s, and in 1974 he landed the role that remains his best known to this day: that of the fourth Doctor on the BBC series Doctor Who. With his trademark hat and scarf, Baker’s version of the Doctor quickly became popular, and in polls conducted by Doctor Who Magazine, he has only been beaten in the “Best Doctor” thrice – and two of those time were to David Tennant. Outside of Doctor Who, Baker’s resume is so varied that it would be difficult to list all of the popular works that he has been a part of, but some of the more notable titles in his filmography include The Chronicles of Narnia: The Silver Chair, The Golden Voyage of Sinbad, The Hound of the Baskervilles, The Magic Roundabout, Little Britain and Little Britain USA. Tom Baker turns 79 today.
