The following sentence relates to the film Fahrenhet 9/11 and its winning of the Palmes d'Or at Cannes: Une Palme d’or à un documentaire engagé, très engagé, cela ne s’était encore jamais vu à Cannes. The Palme d'Or had never before been awarded to a politically committed documentary at Cannes. I'm concerned that I'm missing the nuance of 'engagé, très engagé' in my translation. Can anyone improve this please? Thanks!
