It was unbelievable as a programme, and it's had its ups and downs since then. Personally I think at the moment it's on the up again, do you? What do you think of the new Doctor?" Bonnie replied: "It's fabulous. You know, I was in it once in the 80s, 37 years ago.

.." but Richard cut in with a chuckle: "Black and white, wasn't it?", reports the Mirror .

Indeed, Bonnie entered the world in 1964 just one year after Doctor Who debuted on the BBC with 'An Unearthly Child'. She later joined the iconic series as Melanie, appearing in 20 episodes from 1986 to 1987 and returned for the special Eas.
