I finished my kids' cut of The 36 Chambers of Shaolin.
(Released as Shaolin Master Killer in the west.) It's ham-handed, but we watched it today, and I think it did the job. The guy enjoyed it.
I cut out things that were A) likely scary to my specific kid (like dudes getting gored by spears) and B) too hard for a six-year-old to understand (like Ming vs. Manchu politics).
My main goal, however, was to make it way shorter. I partly got there. The original is about two hours. This cut is an hour and 20 minutes. I was really aggressive about cutting in the third act. The all of the "gathering the posse" and "making battle plans" stuff is gone, and San Te rides straight for the general for the duel.
I left in the trap procession in the first act because it introduced the general, and I left in the trashing of San Te's father's shop by the captain and subsequent escape to Shaolin. That I felt would explain the motivation for training at Shaolin. Those three scenes turn out to be a lot of minutes!
They were unnecessary, it turns out. The guy asked me "Is that a bad guy?" any time anyone showed up on screen. It was very Homer Simpson-esque.
In retrospect, I think I could have simply cut it down to the second (and best) act alone. It would work as a movie about just training to be a Shaolin monk. No backstory or motivation is actually necessary for most six-year-olds. "Here's some tough challenges, and here's this guy doing them" is all they need.
