Aces Go Places IV (1986)
Just when this film series seemed ready to be filed under "Beating a Dead Horse", Karl Maka goes back to the well another time. This time around he hires up and coming director Ringo Lam Ling-Tung to raise the bar a little bit. Lam infuses the film with some of the style he would later find international fame and success with making his "on Fire" trilogy.
The screenplay by Maka moves some the action to New Zealand and continues the same goofy mix of sci-fi and comedy that blends the Hong Kong stars with several western actors. Lam gives the scenario a slightly harder edge than the previous entries. Sally Yeh is a nice addition to the cast.
