It is easier than using larger toys, and it looks very good by comparison, and will take less time to do.
Step 1: Building The Set
- A stand/ground for the characters to walk on
- A background
- Walls on the sides
Step 2: Walking
When making them run, make them kick back as they run. And move their arms with the legs.
When turning, do the same movements.
Step 3: Shooting/Blood
This is to add effects with Lego, you could add effects with a computer program, but putting the Lego in yourself gives the fight a better feel.
Blood may be a little too violent for what you want, but you could still add small Lego blocks to simulate gunfire, and where the bullet/laser is hitting. It could be sparks if you want.
Step 4: Sword/Lightsaber Fighting
Move them at the same time to make it look the best, don't just move one at a time.
When you "clash" swords, move the characters back and forth to simulate them pushing each other.
Lightsabers are a better looking type of sword fight, because of the colors and brighter look to it.
When turning the lightsaber on, you could start with the handle and then add the blade in the next shot, however, it will look much better if you put a small Lego piece on the handle in between the stages of being off and on. It makes it look like a flash, and that the blade is coming out of the handle, so it doesn't just appear on.
