I want to know the answer to the following question:
Which Iranian director won the Palm d'Or at Cannes in 1997?
All the background I'm provided with is that "After the Revolution of 1979, as the new government imposed new laws and standards, a new age in Iranian cinema emerged, starting with Viva... by Khosrow Sinai and followed by many other directors, such as Abbas Kiarostami and Jafar Panahi.". Is that enough to answer the question?
