HONG KONG, May 25 (AP) -- "The Da Vinci Code" and "Mission: Impossible III" may be dominating the box office, but one of the most popular movies online is a six-minute film shot apparently with a mobile phone showing a grumpy man scolding a fellow bus rider in Hong Kong for interrupting his phone call.

"Bus Uncle," as the film is commonly known, has been viewed nearly 1.7 million times on the video Web site Youtube.com -- the second most-viewed video on the site in May as of Thursday -- spawning spoofs and new slang drawn from the ranting subject's emotionally charged soliloquy.

The grainy film, which apparently takes place on the top level of a double-decker bus, is hilarious for its sheer absurdity and the dramatic twists it takes. The lengthy exchange was apparently recorded using a mobile phone.

The film starts out when the protagonist, a middle-aged man, reacts strongly when a young man sitting behind him taps his shoulder to ask him to keep his voice down while talking on the phone.

"I don't know you. You don't know me. Why do you do this?" the infuriated bus rider says, punctuating the sentence by jabbing his right hand downward in the air.

When the young man, who rarely talks back during the argument, expresses an unwillingness to continue the conversation, the middle-aged man explodes, "This is not resolved! This is not resolved! This is not resolved!" -- now a new catch phrase in Hong Kong.

He goes on to say, "I face pressure. You face pressure. Why did you provoke me?"

In another twist, just when the dispute seems to have ended after the young man apologizes and the two shake hands, the young man takes issue with profanity used by the middle-aged man, who then launches into another round of profanities.

The video has inspired numerous spoofs, including a karaoke version and a rap song using the middle-aged man's refrain, "I face pressure. You face pressure." Internet users have also added Chinese and English subtitles.

It still isn't clear who shot the film and it isn't certain if the film was staged or not. The middle-aged man hasn't been identified, but a man claiming to be the victim of the verbal abuse has been interviewed on Hong Kong's Commercial Radio.

"Why did I just sit there? I paid to be on the bus. You don't think I would get off the bus and waste my money, do you?" said the man, identified only as Alvin.
