Well, I would suggest you use the Feng Shui system, if you want a game of fast paced cinematic action. It can handle gun-fu, kung-fu, magic, and unusual creatures like no other game.
If you can get over your aversion to using anything d20, I would also suggest Mutants and Masterminds. While it is nominally a d20 system, it dispenses with classes, has a whole new take on levels, and really streamlines combat (no hit points!). If you can't model a power, gadget, or oddball race with MnM, you aren't really trying. It would give your players something of a break with the d20 system, but cut their learning time by quite a bit.
