Casting.

Here's the resume's of the two leads. 

Annie. Played by Kimberley Nixon

Kimberley has recently risen to fame, starring alongside Judi Dench, Emma Roberts and Colin Firth. Kimberley has a very innocent and young look about her, one that fits the tone of the story well.  Her background is in theatre, which compliments the style of the film, as it is about the interaction between the characters. Kimberley was trained at the Royal Welsh College of Music and Drama in Cardiff, and has performed many plays during her time there, including Road, The Seagull, The Crucible  and the lead in Quadrophenia. She moved on to a television mini series for the BBC, with Judi Dench. Moving on from that, she starred in polar-opposite roles in teen-girl flicks Wild Child and Angus Thongs and Perfect Snogging, and alongside Jessica Biel and Colin Firth in Easy Virtue,  She recently completed a short stint back in the theatre with  Girl With the Pearl Earring. 

Eric. Played by José Manjon

José, of Spanish descent, currently studying at the prestigious Rose Bruford, who's home is at Pontypridd - not far from Kimberley. José has been acting for many years and has played many theatre roles in school performances, such as Bugsy in Bugsy Malone, Danny in Calamity Jane along with roles in Blood Brothers and Grease. He participated in a course with the National Youth Theatre in 2006. This will be José's first ten minute short as the lead. José was selected because his passion for life is a natural starting block for Eric's character. Although José has not tasted as much success as Kimberley, at three years her junior, he has a promising career ahead of him. His background in theatre, as with Kimberley, was a main reasoning in his selection for this role.
