Legendary filmmaker Jonnie To has reunited with Chow Yun Fat and Sylvia Chang for his latest movie Office.

The director from Hong Kong previously worked with the pair in his movie 'All About Ah-Long' over twenty years ago.

Even though so much time has passed, To said it really didn't feel that way when they started working together again.

"They're still very full of energy and their relationship is even better than before and we did say that time when we first made the film together that no matter how good the turn out of this film is, whether it's bad or a success, we were still very lucky just to have the opportunity to work together again after so long and it doesn't really matter what the outcome is like."

The critically acclaimed filmmaker has a film career spanning five decades during which he's directed 54 titles and produced 70 feature films.

Office is set for release on 1 October 2015.
