Hollywood director John Woo, known as a major influence on the action genre, has sent a mail of appreciation to Rajkumar Hirani for his Aamir Khan-starrer 'pk'. The film set a box office record with domestic collections of over Rs 340 crore.

The two had met at the Beijing International Film Festival last year, where they were both part of the jury, and spoken about each other's work at length, says a source, adding: "When Hirani was in China for the launch of 'pk' last month, he had sent a mail to John so that they could meet up. But since the latter was out of town, they could not catch up."
