Jackie Chan almost drowned during the jet ski sequence, when he became trapped in the water under a rock. When he finally came out of the water, director Stanley Tong burst into tears.

Scheduled for January 25, 2020 in China, Vanguard and all films set for release during the Chinese Lunar New Year period have been pulled due to concerns over the spread of coronavirus.
