Mexican actress Salma Hayek said Monday  that President Donald Trump's decision to withdraw the US from the Paris Accord on climate change could only be the direct result of malignity or stupidity.

"I ask myself whether it's stupidity, malignity or greed" that motivated Trump to withdraw the United States from the Paris Accord on climate change, Hayek said without mincing words, as is the social activist's way when it comes to standing up for causes she believes in.

Together with Puerto Rican director Miguel Arteta, Hayek presented the Miami media with her latest film, "Beatriz at Dinner," a smart, tart comedy in which the Mexican plays the part of an immigrant alternative-medicine healer who comes up against the arrogance and self-importance of a real-estate magnate.

During the brief interview, Hayek was quick to describe the intense process of learning to play Beatriz, from studying curative therapies like reiki to taking a course in massage to learning to play chords on the guitar.

What occurs during the film is an informal conversation over dinner among a group of billionaires at the home of the mogul where the therapist Beatriz is staying, and which ends when she tells the guests that the "earth has cancer" and that "you guys think you're safe just because you have money and power," Hayek recounted.

In an atmosphere of comfort and luxury - the film was shot in a Malibu mansion on the California coast - Beatriz speaks out against this world of frivolity and blasts the super-rich real-estate magnate for his blindness in not seeing that "you can't make deals with the planet."

Hayek's big dark eyes flashed with fury when she was asked whether, in that case, she condemns Donald Trump for withdrawing the US from the Paris Accord to stop global warming.

The question one has ask, Hayek fumed, is whether Trump is "so egotistical that he would destroy the planet and everyone on it for his own profit or if he is really just that ignorant."

Trump "is beginning to understand that he can't do what he wants, so he took that decision because he doesn't have to get it past a judge," Arteta said for his part.

"Beatriz at Dinner," with a screenplay by Mike White, will premiere next Friday in Los Angeles and New York, and on June 16 will screen in more than 20 cities around the country including Chicago, Boston, San Francisco, Philadelphia, Miami, Dallas, Houston and Seattle.

The adversary of Beatriz in the movie is the cynical, implacable magnate Doug Strutt, meticulously played by John Lithgow, whose world of "winners" clashes at a dinner with the impassioned, compassionate Mexican therapist.
