Bowker first came to international attention as the star of The Adventures of Black Beauty (1972), a television series which was a continuation of the book.
She also recalled how some of the Black Beauty episodes were set in springtime, but filmed in winter, so that sometimes she had to wear summer outfits in cold weather.
[3] Also in 1972 Bowker starred as Saint Clare of Assisi in Franco Zeffirelli's Brother Sun, Sister Moon.
[5] She has appeared in numerous theatre productions including major roles in Hedda Gabler, Macbeth, Ivanov, A Midsummer Night's Dream, Three Sisters, and in her husband Harry Meacher's adaptation of Sherlock Holmes.
[7] Bowker has been married to the actor Harry Meacher since 1979[8] and, as of 2017, have lived near – and worked in productions at – the Upstairs at the Gatehouse theatre in Highgate for decades.
