Jane Asher – 75

She debuted on the big screen as a child actress, and surprisingly enough, Jane Asher is still acting in her mid-70s. It’s not always that child actors continue in the same line of work as adults, but Jane’s thankfully managed to last through time. She may no longer be the six-year-old playing on Mandy in 1952, but she has many projects announced for the future. In fact, her IMDb page mentions two films for the years to come, Splinter and 3 of a Kind. Meanwhile, she’s known for series like Jackanory and films like Deep End, and I Give It a Year.
