DAVID Threlfall may be known to most as one of TVs scummiest characters ever – but now he's set to take a completely different role in Troy: Fall of a City.
Here's everything that you need to know about the star…
David is a 64-year-old actor of both the stage and screen from Manchester.
The star studied his craft at the Manchester Polytechnic School of Drama before getting his break and debuting on screen in 1977.
Since then, while landing some TV roles, he has mainly worked in the theatre, taking on parts including Oedipus, McBeth, and Don Quixote.
He has been married to Bosnian-British actress Brana Bajic since 1995, and the pair have two children.
To most, David will be recognisable as Frank Gallagher in the UK version of comedy-drama series, Shameless.
On film, his credits include Hot Fuzz, Elizabeth: The Golden Age, Master and Commander and Alien Autopsy.
However, most of his screen credits have been in TV roles, both comedic and dramatic.
In 2016 he starred as Abel Croker in Ripper Street, and he has also appeared in shows including Tommy Cooper: Not Like That, Like This, Afterlife and The Romantics.
The eight-part series will portray the epic story of a battle between mortals and gods – and the origins in which set the wheels in motion for the siege of Troy.
Louis Hunter and Bella Dayne play the lead roles of lovers Paris and Helen, whose love affair brings society to its knees.
Told from the perspective of the Trojan royal family at the heart of the siege, Troy: Fall Of A City "is a rich story of love, intrigue, betrayal and belonging".
Creator David Farr said: "I’m delighted we’ve assembled such a high-quality ensemble cast, mixing some exciting new faces with experienced actors whom I have long coveted and admired."
Troy: Fall Of A City starts on BBC One at 9.10pm on Saturday February 17, 2018.
If you miss it, you can watch it again on the BBC iPlayer.
The show goes up against QI XL on BBC Two, ITV's The Voice UK and Ted 2 on Channel 4.
It will be available on Netflix internationally.
