Here's some simple rules to make the game a LOT more cinematic:
1. Escalating Combat: Everyone's base attack bonus and caster/manifester levels are limited to the number of the round of combat you're in. Meaning, during round one, everyone has +1, and casts as a first level caster. Second round, it goes to 2, third round to 3.....
Really good for forcing those protracted PC vs. Villain fights. What's even more fun is that it's good for suspense, because the players have no idea how powerful the enemy really is.
2. The 'Hey Guys Watch This' Rule: Once per session, a player can say "Hey guys, watch this!" and attempt a non-attack related action. Roll a d20, DC 15, no other modifiers. If they succeed, they succeed completely in what they wanted to do, and look really cool doing it. If they fail, they REALLY screwed up.
3. Overrun rule: When you want to throw unending hordes of minor enemies at the players, but still give them a chance for victory, use this one. It's simple. During the fight, if a weenie enemy takes enough damage to put them down, but not enough to put them at negative their original hp total, another identical enemy just like fallen one enters the fray from somewhere off camera.
4. Feng Shui Rule: Based on the roleplaying game by the same name. It's simple. If the player does something really cool during an attack, that has no other real effect except looking cool, they are considered to take 10s on the rolls to do that thing, despite being in combat. For instance, provided their skills are good enough, the player who wants to jump, grab a hanging rope, swing across the room, flip into the air, and come down upon the orc sword leading can do the jump. grab, swing, and flip with no rolls, because the effect is exactly the same as if the character charged across the room. As long as the end effects are the same, the player attacking the orc, don't force them to roll to make it look cool. In fact, if what they do is REALLY impressive, give them a +1 to hit. Call it a 'pinache bonus'.
5. Why Won't you Die??!!: Based on Inigo Montoya. At any time, characters may spend xp to heal themselves for a d8 of hp per 25 xp spent. Doing so leaves them stunned for one round, though.
