CHALLENGE OF THE TIGER (1980)

 This is one of the wackier kung-fu flicks I've seen in a while. It also seems to have a bit of a bigger budget since it appears to have been filmed in Asia and Spain with a few caucasian stars thrown in for variety. Directed by, produced by and starring, Bruce Lee imitator Bruce Le, the plot deals with a couple of C.I.A. agents(Le and Richard Harrison) having to obtain some secret formula to make males infertile from evil neo-Nazi mobsters. Harrison does a James Bond shtick and lets Mr. Le do most of the actual fighting. More importantly than this though is that he directed the insane slo-mo topless tennis-playing scene that is really the stand-out part of this film that you will remember after after this else has faded from your memory. Bolo Yeung shows up for a little bit as part of another rival gang. I almost thought my long-standing wish of seeing Bolo play a heroic role would happen when he gets double-crossed by his no-good boss but this is sadly cut short. You do get to see Mr. Bolo go up against a white dude(Brad Harris, a former HERCULES star amongst other things) who actually has bigger arms than him which is a very rare occurrence. Le is fine as the heroic star(he gets to toe-to-toe with a rampaging bull, some guys on motorbikes, the aforementioned big-armed hulking white fellow and a whole slew of chopsockey-fodder) but I think I'm still in the Bruce Li camp as my personal fav Lee-rip-off actor. The real star of this thing though is all the ample nudity on display. You're pretty much guaranteed to see every female that shows up in the buff at some point which is quite a departure from your standard Hong Kong fu flick. True exploitation for the discerning palate. AKA SEIZE THE FORMULA and GYMKATA KILLER
 According to IMDB an alternate title for this in Bolivia is ZOMBI 7-11: ENTER THE ZOMBIE which makes no fucking sense at all!

Released as GYMKATA KILLER on video to cash-in on the popularity of GYMKATA at the time:

English spelling is apparently not very important on Egyptian posters!(also that bottom left drawing looks like Don Knotts in drag which is a bit disturbing!):
