Runtime of the original version: 122:56 min (with end credits)
Runtime of the British DVD: 120:24 min (with end credits)
The UK Version had to be cut to obtain a BBFC 15 rating. Beside the cuts the sound intensity of every punch, kick etc. has been reduced. This is not further mentioned in this article. (Thanks to Gavin Salkeld for providing this information)
33 cuts = 87,74 sec
The fight, when Wah Sing Ku ambushes the escaping Triad members on the roof, was cut numerous times in the British version:
Wah twists the smalltime criminal's arm.
He steps on his foot, grabs his open mouth and pulls him down to hit him with his knee.
When the choking with the chain occurs, a close-up of the Triad member's throat, grasping for air, was removed.
Another shot of the strangled throat is also missing.

Shortly thereafter he hits him in the face with his knee.
The cop is being kicked so hard, that he falls over backwards over a table.
Riggs headbutts his opponent again.
After the gangster falls from the transporter onto the street, the shot of him getting run over by another truck is missing.

There are two cuts in the scene with the delivery of the counterfeit money:
The close-up shot of the two Triad members getting killed by headshots was cut.
After Wah brought down an opponent, the shot of him breaking his neck with his legs is missing.
The final battle between Riggs, Roger and Wah Sing Ku was cut the most:
Wah kicks Roger so hard in the stomach, that he can't breathe.

After Riggs dislocated his arm, the shot of Wah painfully pulling it is missing.

Again, all the strangling and thumb pushing is only to be seen in the original version.

The shot of Riggs grabbing both ends of the pole and pulling it around was cut.
After Riggs lifts up Wah by the pole, a far away shot and a close-up of the events are missing.
A close-up of Riggs shooting Wah Sing Ku with the rifle underwater was cut.
