The main attraction - Jaycee Chan caught with his pants down

At Thursday's Hong Kong Asian Film Festival opening press conference, it was announced that more than 80 films would be shown between September 23 and October 10 - with two of the top attractions, director Jiang Wen's The Sun Also Rises and Edmond Pang Ho-cheung's Exodus, already sold out.

But most of the media pack just wanted to hear from Jaycee Chan Cho-ming (right). It seems there are pictures of Jackie Chan's son from a scene in The Sun Also Rises on the internet.

In the movie, Chan's bare behind is shown as he relieves himself, but someone has leaked (pardon the pun) a picture of him from the opposite angle showing a tube filled with yellow liquid taped to one of his legs and up around his groin. It would seem that the young Chan is not too pleased to be caught with his pants down.

'I don't mind having pictures shown of my backside, but those from the front was just a bit too much for me,' an embarrassed Chan said. 'I have already told the staff on set not to even use mobile phones in case they use that to take pictures of me.'
