With regard to aid for the pre-production and production of immersive works, the total amount of aid granted for the same work may not:
1° Exceed 50% of the final cost of the work and, in the case of an international co-production, 50% of the French participation;
2° Have the effect of increasing the total amount of public financial aid to more than 50% of the final cost of production of the work and, in the case of an international co-production, more than 50% of the French participation.
Exceptions to the 50% threshold may be granted by the President of the Centre national du cinéma et de l’image animée, up to a limit of 80% and at the justified request of the production company, for difficult works. A difficult work is one that is innovative or not easily accessible, particularly in view of its subject matter, format, dramaturgy, direction or production conditions.
