Jessica Chastain, who is set to star in the Canadian director's next movie, tweeted: "Forever proud of you baby!!"

Count Jessica Chastain among Xavier Dolan's biggest fans, just as his native Canada on Sunday applauded the young director's Grand Prix win Sunday at the Cannes Film Festival.

"CONGRATS @XDolan on Grand Prix!!!! Forever proud of you baby!!!," Chastain tweeted after Dolan won the second-place trophy in Cannes for his family drama It's Only the End of the World.

"@jes_chastain thank you honey! I am so so so touched! Can't tell you what the Emotion here is like!" Dolan replied on his own Twitter account to Chastain, who is set to co-star along with Natalie Portman in the Canadian director's first English-language movie, The Death and Life of John F. Donovan.

Dolan got into another Twitter exchange with film blogger Jessica Kiang, who wrote: "I think Cannes might just have ruined Dolan forever. No chance he's going to rein it in now." Dolan dismissed Kiang's criticism with his own tweet: "I'll be alright, Jess. As long as I ignore your cheap parallelism between a life you don't know and a play you've never read." 

Dolan's defying critics to pick up the Grand Prix, along with the Ecumenical Prize on Saturday, stirred pride back in Canada. "Dolan’s two latest awards at Cannes are renewed recognition of his immense talent, of course, but also of the determined effort and sheer perseverance he has demonstrated from the outset. For all those reasons, he is a source of pride for us and for all Canadians," Carolle Brabant, executive director of Telefilm Canada, the country's biggest film financier, said in a statement following Dolan's wins.

Emily Hampshire (12 Monkeys), who is also set to appear in The Death and Life of John F. Donovan, also applauded the Grand Prix win on her Twitter account: "This. Is. An. Artist!" It's Only the End of the World stars Vincent Cassel, Marion Cotillard and Léa Seydoux and portrays a man who returns home after a long absence to tell his family that he is about to die.

Dolan in 2014 grabbed the third place Jury Prize for Mommy, a prize he shared with French director Jean-Luc Godard. It's Only the End of the World is the director's sixth film, and the fifth to screen in Cannes.
