According to Universal France, Marion Cotillard and Guillaume Canet will lend their voices to the villains Scarlett and Herb Overkill in the upcoming animation film Minions. Sandra Bullock and Jon Hamm give those characters their voices in the English spoken version. The film will release July 10 in the United States and July 8 in France.
I found a trailer for the French version with Marion’s character in it. She has disguised her voice a bit but you can hear it here and then when she speaks… I think?
