This is disgusting. Whatever greedy and seedy shit is going through the head of the producers, this isn't respectful nor appropriate as an homage to the artist's life or the art form. Get a good talented star that can both act and sing and pay her lavishly to interpret Piaf in the biopic. Piaf's soul and memory would be more solemnly honored by the young people entering the art learning and singing her songs than by a cold heartless machine making a pantomime of what a human sounds like.

I can't wait to completely forget everything about this movie thirty seconds after moving on from this post.
Hollywood has "spend" problem. This seems like a movie that deserves to be lovingly crafted and acted by people who care about the source material and with a relatively low budget so that it is easy to recover the cost and feasible to make more of its kind. Instead, they're going to make a tech abomination for at least ten times the amount that it will gross.
Ah, great, who needs actors?? Finally, talent that can be possessed and owned without pay!
This AI nonsense has gotta stop, it's just more excuses for wealthy people and companies to stop paying people for work.
This song was never supposed to become reality. I hope everyone involved ends up haunted until they pass themselves.
