Veteran actress Shabana Azmi has expressed her disapproval over the Cannes Film Festival's practice of only allowing women in heels at the gala.

The 64-year-old actress, who has attended the festival in the past and also served as a jury member, said she was shocked to read reports that women in flats were denied entry at the festival.

"Shocking report that Cannes bans flats on red carpet! Director of 'Amy', Asif Kapadia says his wife was given rough time too. Unacceptable surely," Azmi posted on twitter.

Earlier Hollywood actress Emily Blunt had also criticised the Festival's reported practice though festival director Thierry Fremaux had denied that there was any such rule.
