We hardly recognise these A-list celebrities from back in the day!
ITV police drama, The Bill, was a house hold favourite soap back in the day, running for 26 years from 1984 until 2010.
The weekly drama series followed the lives of the police officers at the fictional Sun Hill Police Station in East London.
Recently, on demand service UKTV has seen a rise in the number of viewers taking a trip down memory lane and revisiting the old episodes - and fans have been picking out the celebrities who started out on the show.
Here are some of our favourites and we had no idea they were in The Bill!
Who would've thought that before she hit the big time as a Spice Girl, Heart's very own Emma Bunton appeared as a troubled teenager in an episode aired in 1993!
Who knew that this ten-year-old thief would go on to be one of the biggest names in Hollywood! Keira played Sheena Rose in an episode are in 1995.
This funny man once played an animal rights activist back in 2002. Little did he know that one day he'd be sitting on a judging panel alongside Simon Cowell on Britain's Got Talent.
Before he became a Hollywood superstar, the Game of Thrones actor starred in The Bill.
In 1995, David Tennant played a dodgy Stephen Clemens who was brought to justice by the police. Now, there's no stopping the tenth Doctor Who.
He once played Gavin Donald, a Scottish boy who is interviewed about a hit-and-run, back in 1997. He went on to play Mr Tumnus in the Narnia Chronicles and Charles Xavier in X-Men.
Billy Case was accused of assault in 1994 but the actor who played him went on to have a career in comedy and acting. AND he married (and later divorced) Katy Perry.

He's always played those slightly thuggish characters and this one was no different. Ray played Simon Fielder who was interviewed about some boys who went missing. Now you'll know him from The Departed.
The Doctor Who star had a long running career on the show from 1984 to 2009.
Who'd've thought it eh?
