Marion Cotillard has few kind words for Brad Pitt amid the constant rumours regarding his high profile divorce with Angelina Jolie. The French actress, who was linked to her Allied co-star soon after Jolie filed for divorce, gushed about Pitt in a recent interview.

"He such a good man. Of course, he's an amazing actor. He's such a good person that it's really not difficult to get along with him," the 41-year-old actress told ET Online.

Cotillard is thrilled about her onscreen chemistry with the 52-year-old Hollywood actor in her upcoming movie Allied, a spy thriller set during the Second World War.

"Sometimes, you never know. Sometimes, you have nothing in common, no chemistry, and it still works on screen. You have many different situations, but we had this chance to have this period of time to get along together, so it helps," she told the publication.

The romantic mystery is based on Canadian intelligence officer Max Vatan and French Resistance fighter Marianne Beausejour as they fall in love during a secret mission behind enemy lines. The couple eventually tie the knot in London but that's only the beginning of the mystery as the authorities suspect Marianne as a German spy. Going on the plot line, the movie needed Pitt to have a French accent which, according to Cotillard, he did an "amazing job."

"I know how hard it is to learn another language. I had to go from French to English and still struggle with some sounds sometimes, but I was very impressed [with his commitment to work on] his French," she added.

The French actress is currently pregnant with her second child and was blamed for the highly publicised separation of the former Hollywood couple. However, she later cleared the air claiming her innocence in the whole divorce drama.

Allied is directed by Robert Zemeckis and set to premiere on 23 November 2016 in the US and on 25 November in the UK.
