In 2010, Serge wrote and recorded the score for the film London Boulevard, starring Keira Knightley and Colin Farrell. The London Metropolitan Orchestra recorded the strings for the score. This video, hosted by @LondonMetropolitanOrchestra, who is the conductor of the orchestra, shows a little insight into recording the strings for the film, particularly the track known as The Green Fairy.
The Green Fairy went on to be known as La Fée Verte.
