At one point she stifled a yawn, looking rather bored with the media obligations.
Not so for Kristen Stewart, who chucked her high heels at last night's "BlackKklansman" premiere, either because she's still smarting from the rumored flat-shoe ban or she simply got sick of wearing them on a rain-soaked carpet.

Walking arm in arm with 82 other women which included Kristen Stewart, Patty Jenkins, Salma Hayek, both she and Palme d'Or winning director Agnes Varda gave moving speeches that set the tone for the festival. At the base of Cannes' intimidating staircase, she made a bold statement when she removed her shoes after a photo call and scaled the steps barefoot into the theatre.
She has been a vocal opponent of the heels rule. The girl plays the lead in a survival story together with her father, enacted by Angel Leonel Corral, in a country with drug problems strongly rooted in the whole society.

However, in 2015, it was rumoured that a group of female invitees were turned away from the opening of Cate Blanchett film Carol for turning up in flats.
Only 82 female directors have ever competed for the festival's top prize, the Palme d'Or, since 1946 compared with nearly 1,700 male directors.
