Take your pick from our selection below...
The Biggest Breakthrough Screen Stars Of 2014
Jamie Dornan(01 of10)
This time last year, Jamie Dornan was another model-turned-actor. Now, he's the creepy star of 'The Fall', holding his own against Gillian Anderson, and, oh yes, the star of the screen adaptation of the biggest publishing phenomenon of the decade. Step forward, Mr Christian Grey!
Felicity Jones(02 of10)
After sharing the screen with Ralph Fiennes in 'The Invisible Woman', Felicity Jones topped her year with a performance that will surely be garnering her awards in the new year - playing Stephen Hawking's devoted but troubled wife Jane in 'The Theory of Everything'.
Douglas Booth(03 of10)
Douglas continued his crusade on the big screen, first in Biblical epic 'Noah' and then in toff-bashing satire 'The Riot Club'. On its way, 'Jupiter Ascending' alongside Eddie Redmayne, as well as the role of Mr Bingley in 'Pride and Prejudice and Zombies'.
Maisie Williams(04 of10)
This Bristol-born teenager continues to light up the screen, as her role of Arya Stark becomes increasingly dynamic and central to the 'Game of Thrones' narrative. Away from the dungeons, Maisie's proved herself in films 'Gold', 'The Falling' and the forthcoming TV movie 'Cyber-Bully'.
James Norton(05 of10)
After thrilling and chilling audiences as villain Tommy Lee Royce in Sally Wainwright's 'Happy Valley', James took up his cassock for the lead role in ITV's new crime drama 'Grantchester'. Co-star Robson Green tips him for great things. "It's a matter of when, not if." In the meantime, a packed parish for every sermon.
Archie Panjabi(06 of10)
With her continuing role in 'The Good Wife' making her a famous face Stateside, the 'East is East' actress stood out this year in homegrown dramas 'The Widower' and then 'The Fall', where her tantalising relationship with Gillian Anderson is as unpredictable as the movements of the killer they're both tracking.
Richard Harrington(07 of10)
17 years after his first TV role in 'The District Nurse', and following a decade of respectable character roles, Richard Harrington is the star of his own series - as troubled detective Tom Matthias in 'Hinterland' . Now a hit on Netflix and being shown across the world, this promises to do for Wales, and Richard, what 'The Killing' did for the Danes.
Maggie Gyllenhaal(08 of10)
A year ago, Maggie Gyllenhaal was the relatively unknown sister of Jake, and a member of a respected screen and stage acting family. That was before 'The Honourable Woman' TV series, where her role as Nessa Stein proved what she could do with her soulful, intelligent gaze, as well as her way with an impeccable English accent.
Aneurin Barnard(09 of10)
This Welsh actor was doing well before, but with roles mostly emphasising his Elijah Wood-esque pixie presence, eg Richard III in 'The White Queen'. Playing Bobby in Jeff Pope's biopic 'Cilla' proved him to be believable as a dashing, seductive lead, and can even get away with a bright blonde barnet.
Cara Delevingne(10 of10)
Supermodel - tick. A-list party pals - tick. Now it's time to be a respected screen actor. Ok, then. Within two years, working for directors including Michael Winterbottom and Justin Chadwick, this covergirl has proved to be a compulsive screen presence, of whom we can expect great things.
