Abstract
The Russian studios played a considerable part in animation. Which elements allowed this success? How did they reach the excellence? How did they reconcile artistic freedom with ideological pressure? Soyuzmult Film benefited from considerable meansboth on the human and financial plan and developed a big variety of techniques. The productions of studios drew from immaterial heritage of Russia but aimed at universality to reach the widest public. The quality of the realizations which rested on the notion of author and style, the reflexivity and the intermediality, contributed in the success of Soyuzmultfilm. Nevertheless it is advisable to question this success, to highlight the ambiguity of the model, which develops a propaganda sometimes visible, sometimes discreet, according to period. The omnipresence of the theme of the dream appears as the symptom of a powerful censorship. A movie as 25th October, 1st day, of Youri Norstein, could constitute the emblem of a censored propaganda.
