Timecop
As you say Reservoir Timecop remains his most popular, unfortunately I think the runner-up was the sub-par Streetfighter. I think talks of a sequel to the latter film have finally fell through. The reason I heard for him not wanting to do the helicopter kicks anymore was indeed that he himself felt he was getting too old for them which is a shame. There aren't many Van Damme films I haven't been keen on, only Black Eagle, Streetfighter and Derailed really. He seems to be becoming a very decent actor lately, which Ringo Lam has made shine through in his recent films. I have high hopes for Wake of Death being what Out For a Kill should have been (don't get me wrong I still love Out For a Kill despite its flaws), I wonder whatever happened to The Tower and The Monk?
