Former Cagney and Lacey star Sharon Gless has taken on on a very different role - a surgeon on Casualty!
She joined the new series of the BBC medical drama as Zsa Zsa Harper-Jenkinson, but we know her best as Christine Cagney (opposite Tyne Daly's Mary Beth Lacey).
The Golden Globe-winning actress, now 74, says: "Zsa Zsa is a wonderful character and I hope everyone else enjoys her too."
We can't wait to see how she gets on! See what else this series of Casualty has in store by watching the trailer.
