Today is the birth centenary of one of a handful of Hindi film actors who managed to cross from one type of role to another—again and again. Like Ajit, Pran, and Premnath (though not in the same league as them, when it came to success and popularity), Sajjan Lal Purohit—better known simply as Sajjan—appeared in leading roles in several of his early films (including, notably, in Saiyyaan, where he acted opposite Madhubala), then drifted into supporting roles (as Dev Anand’s sculptor friend in Paying Guest; as Mini’s father in Kabuliwala; and more), and eventually into villainous roles (in April Fool, Aankhen, Farz, etc).
