France, May 21 -- French composer Alexander Desplat and Mexican filmmaker Guillermo del Toro came together at the Cannes Film Festival to share anecdotes oftheir longstanding artistic collaboration, and underlined the importance of music in the filmmaking process.

La lecon de musique - The Music Lesson - is an annual event at the festival organised by Sacem, the French authors' rights company, to promote the talent and contribution of composers in the film industry.

In her opening remarks, Sacem director Cecile Rap-Veber said she was shocked that there is still no official prize category for music at Cannes and urged the film festival's chief Thierry Fremaux, who was present at Sunday's event, to create one.
