here's the original Mandarin trailer for SUPER INFRAMAN. I'm kind of surprised it doesn't have subtitles, but it's pretty straightforward. in fact, so much so that you get nearly the entire movie in under four minutes. this seems to be pretty standard for HK movies. I wonder if there was ever an "international" trailer in English for this movie. I know several were made. heck, I wonder if there was a different English dub made for this one as well.
I posted the US trailer here, with a small amount of controversy. it's fun to compare both trailers.
