17. Yasmin Paige.
16. Sacha Parkinson.
15. Dakota Blue Richards.
14. Asa Butterfield.
13. Arthur Darvill.
The Form: Rory in Doctor Who, of course.
The Buzz: Darvill’s everybloke charm took Rory from bit player to one of the most beloved companions ever, and along with Karen Gillan he’s facing one of the more successful post-Who careers.
Next Up: A steady stream of stage work, before a second series of Broadchurch next year.
12. Maisie Williams.
The Form: Williams won significant acclaim as Ayra Stark in the already-crowded cast of Game Of Thrones.
The Buzz: At 15 she is the youngest ever actress to win a Best Supporting Actress Portal Award, the same year that she was submitted for consideration at the Emmys. She also caused an internet fuss with that Red Wedding Vine.
Next Up: Thrones will keep her busy for a while, but there’s film roles on the horizon in Gold and We Are Monsters.
11. Craig Roberts.
10. Katherine Kelly.
9. Bronagh Waugh.
8. Damien Molony.
7. Emmett Scanlan.
The Form: As tortured gay gangster Brendan Brady, Scanlan was the undoubted star of Hollyoaks for three years, and his line in psychopaths extended to acclaimed indie movie Charlie Casanova.
The Buzz: The Dubliner owned the screen and brought Hollyoaks more acclaim that it had done in years. He’s picking his post-soap projects well, appearing alongside former co-star Bronagh Waugh in The Fall. So good we've bent the rules and put an Irishman in.
Next Up: As well as the second series of The Fall, he will star in independent movies Lapse and Patrick’s Day.
6. Jack O'Connell
5. Freya Mavor.
4. Emun Elliott.

The Buzz: He’s working his way up, but Elliott looks like a surefire leading man in the making. Also: fit.
Next Up: A second series of The Paradise is on the way.
