But all the young actors pictured, right, have been tipped for success by the influential film industry magazine Screen International.
Rebecca Hall, the daughter of the director Sir Peter Hall, and Dan Stevens and Hayley Atwell, both seen in the TV adaptation of Alan Hollinghurst's Booker Prize-winning novel, are among the names being hailed as the next generation of British stars.
Others include Riz Ahmed, who appeared in Michael Winterbottom's The Road to Guantanamo, Nonso Anozie, who was acclaimed for his Othello with the Cheek by Jowl company, and Simon Woods, who played the endearing Mr Bingley in Pride and Prejudice with Keira Knightley.
Two potential stars, both chosen to appear in the Zoe Heller adaptation Notes on a Scandal alongside Cate Blanchett and Judi Dench, are still at school. They are 16-year-old Juno Temple and Andrew Simpson, 17.
Several casting directors singled out Joe Anderson for "his unconventional good looks and charming personality". He is currently shooting the romance Becoming Jane alongside Anne Hathaway and James McAvoy and will then make Copying Beethoven with Ed Harris.
Des Hamilton, a casting director, told Screen International that Thomas Turgoose, who stars in This is England, Shane Meadows' film about fascist skinheads, had made the best screen debut he had seen in years.
The final actors on the Screen talent list are Jodie Whittaker, currently appearing in Enemies at the Almeida theatre in London, and Andrea Riseborough, who left Rada last year. Both have just shot Roger Michell's Venus alongside Peter O'Toole.
But the magazine also picks the hottest talent among new producers, directors and writers, too.
With these, it has particular form. In 2004, it chose Andrea Arnold, whose film debut Red Road has just won the Cannes jury prize, and last year it featured Mia Bays, who this year won an Oscar for best short film.
Among its new tips for success are two brothers, Ben and Chris Blaine, writer-directors who have produced a series of award-winning shorts and are now working on three features.
Others include Jamie Johnson, a director making short films for Channel 4 and adverts, Krishnendu Majumdar, a director who has made uncompromising TV documentaries such as Who You Callin' a Nigger? and Lucy Moore, a writer, whose first script, Gone, was described by one commissioning editor as the best first script she had read.
Tristram Shapeero, who directed the Channel 4 comedy series Peep Show, Green Wing and Brass Eye, is being touted to move into film.
Some talents on the Screen International hot list have made bigger leaps than that. Barrington Paul Robinson spent 15 years working in finance before becoming a producer while Laurence Belton, a writer, trained as a lawyer.
The other chosen talents are: Miranda Bowen, Corinna Faith, Daniel Mulloy, Tom Harper, Robert Morgan, Gabriel Range, Simon Finch, John Williams and Chris Waitt, all writer-directors; Laurence Relton, Kate Hardie and Richard Warlow, all writers; Jane Hooks, David Smith, and Wendy Bevan-Mogg and Izzy Mant, all producers.
