I still remember the episode where a boxer is laying on the rubdown table and the janitor sneaks in and whacks him across the knuckles as hard as he can with a crescent wrench.
Also, seeing the dead Chin Ho being thrown out of a moving car and rolling to a stop was one of the more chilling scenes of the entire series to me.
I'll never forget that, I was pretty upset they did that.
In 1997, CBS made a 2 hour “Five-O” movie that was supposed to be the pilot for a revival (long before the current one).
It starred Gary Busey and most of the original cast who were alive then put in an appearance. It has never been seen outside the halls of CBS.
Reason being that they hired Stephen J. Cannell to produce it (even though he had never seen Five-O....watched a few episodes to get the gist of it). Among the actors used in the pilot was Kam Fong, who played Chin Ho Kelly (even though Chin Ho was killed off in the episode you mentioned....season 7, I believe)
Nobody involved with the original said anything because Kam Fong was in ill health and having financial problems. None of his former co-stars wanted to deny him the paycheck.
The story goes that when they screened this at CBS in New York, some intern noticed and pointed out that Chin Ho had been killed off. Reportedly sending Cannell right over the edge. By that point Fong had cashed his check, and there was nothing that they could do.
I would love to see this if it ever comes out on video.
