Viewers of ITV's new drama The Thief, His Wife and the Canoe couldn't quite believe it, as two familiar faces popped up in the show.
As the drama based on real events concluded on Wednesday, John and Anne Darwin were interrogated by police about their dishonest plot - that saw John fake his death in 2002.
In the scenes, detectives tried to work out what exactly the couple had planned, and whether Anne had known about the plot the entire time.
While Anne was shown denying having any knowledge initially that her husband John had faked his death, John was shown suggesting he had no clue about Anne collecting the money from his life insurance policy.
As the interrogation continued, and during other scenes earlier in the drama, fans were quick to recognise two familiar faces.
The detectives grilling both Anne and John were none other than Coronation Street and The Bill actor Andrew Lancel, and comedian and actor Karl Pilkington.
Racing to Twitter, viewers were quick to point this out, with many calling for the duo to pair up in a reboot of ITV police drama The Bill.
One viewer said: "I recognise the interviewing officer as being in the Bill. Not Karl Pilkington. The other one."
Another tweeted: "This is just reminding me I still miss The Bill and why wasn't @AndrewLancel character just called Neil Manson? I mean, he'll always be Manson... maybe Chief Constable now though...."
A third added: "Omg did anyone else spot DCI Neil Manson interviewing John Darwin? Or am I just a die hard fan of The Bill?"
The comments kept on coming, with another tweet reading: "No way, The Bill and Karl Pilkington are in it, and was Karl trying not to laugh?!"
A fifth viewer tweeted: "CID scene thoughts: seeing Andrew Lancel sat back on a chair gave me strong flashbacks to The Bill… then ‘is that Karl Pilkington!’"
The Thief, His Wife and the Canoe is available to watch now on ITV Hub.
