One of those cheap, sunny action films that seemed to proliferate in the 1980s and always went straight-to-video in the days of the VCR boom. The twist is that this is a Ted V. Mikels film and so cheap that it wasn't actually released until 1991, even though it was shot in 1982 and feels very much like an early '80s movie. It's also the best Mikels film I've seen so far, but only because the other films I've seen by him (including BLOOD ORGY OF THE SHE-DEVILS and TEN VIOLENT WOMEN) have been much worse.
The storyline makes a fair bit of sense and involves some terrorists getting their hands on nuclear weaponry. A fashion magazine serves as a front for criminal activities so there are lots of padded photo shoot scenes involving women in bikinis (and occasionally out of them) wandering around swimming pools and beaches and the like. Unfortunately not many of them are very attractive and there are some you really don't want to see so much of. The bad guys include mercenaries and corrupt officials, while the sole hero is a Chinese guy played by the little-known martial artist Tiger Yang who just so happens to be a government agent.
Yang isn't much of a hero, it has to be said, although he's still better than Leo Fong of LOW BLOW infamy. He gets to kick and strike his way through various henchmen in a series of cheap and cheesy fight scenes. In some respects, MISSION: KILLFAST reminded me of the delightfully inept movies made by Amir Shervan, such as KILLING American STYLE and SAMURAI COP, although sadly it's never as deliriously awful as them.
