Meanwhile, in Hong Kong, Buck Yuen, an exercise equipment salesman, inadvertently foils a bank robbery and becomes a media celebrity.

After Park's death, Yuen scatters his ashes at his wife's grave and finds a message ("wait for me") engraved on the tombstone.

In Istanbul, Yuen uses the crucifix, which turns out to be a stamp, to retrieve the contents of Park's safety deposit box.

Yuen recalls that there was a Bible in the safety deposit box so he makes his way to a nearby church and meets a priest who knows Park.

After Yong dies at the train station, Yuen gets arrested and thrown into prison but Carmen and Ashley bail him out.

Carmen, feeling sorry for Yong's death, secretly reveals to Yuen that the CIA is meeting Zen the next day to discuss buying the Anthrax II from him.

After Yuen manages to save the driver and his son, the tanker is heading straight towards the edge of a disused bridge.

When Yuen regains consciousness in hospital later, he learns from Liu that his entire adventure was actually a CIA mission arranged to be performed by him as an informal, non-official agent (an "accidental spy").

The dream of his parents is actually an illusion created by Liu, who added drugs into Yuen's drink to put him into a hypnotic state.

In a post-credits scene, Yuen, now officially a spy, delivers a briefcase to a drug dealer in Italy and tips off the police to arrest him.

Like many Jackie Chan films distributed by Disney, scenes were cut, foreign dialogue was dubbed, and the music score was changed.

On 19 March 2009, Kam & Ronson released a remastered DVD with an anamorphic picture, 5.1 and DTS sound, but with no special features.

The scene of Buck's disguising while escaping from thugs was reproduced in Bollywood movie Thank You (2011), wherein Akshay Kumar's character, detective Kishan, also hides by twisting hanging materials around himself.
