Gee, wauw! Another unknown/forgotten/semi lost post-apocalypse film from the Philippines!!! This one has even turned up on DVD. :D
THE SISTERHOOD is listed as a strict American production on IMDb. I asked Henry Strzalkowski (who is in the film) about it on Facebook and he confirmed what I already suspected; The movie is made 100% in the Philippines!! Unfortunately, a lot of non-American films are listed on IMDb as American productions or co-productions if there's just one American actor in them. Needless to say this isn't correct. If it were the case about 75% of all American films would have to be listed as being British or European. The IMDb is all right as a starting point for research but it's not all that good on its own.
Henry Strzalkowski about shooting THE SISTERHOOD:
"Completely filmed in the Philippines, directed by Cirio Santiago. Great find, Jack! Haven't seen this one. That's me at 0:07 [in the trailer]. During a sword-fight rehearsal, [Lynn-Holly Johnson] accidentally struck one of our stuntmen. Actually she lopped off the end of his index finger. Since we were using dull aluminum prop swords, she more or less crushed it. The stuntman was Greg Rocero. I'll never forget seeing him just wince and stop. When he pulled out his hand, we realized what happened. He went straight to hospital and showed up about a couple hours later (with his severed finger in a bottle, I'm not joking). I asked him why he was back and he simply said, "I gotta drive my truck back." I asked him if it hurt and he said, "It just throbs a bit." What a guy... All in a day's work. The risks you take. Lynn-Holly was devastated. For the rest of the picture."
THE SISTERHOOD is released on DVD in the UK and I believe the UK DVD is the only release on DVD. I haven't been able to find one single VHS release! It's available from Amazon UK. I've ordered a copy but haven't received it yet so I can't comment on the picture quality. The Amazon page lists the film as being in widescreen.
EDIT: SISTERHOOD was released on VHS in the US. See scan in the above. Thanks to GARY MILLER of DVDManiacs for the info and scan!
