When we set out to make "Star Wars : Macbeth," we knew that we would
be giving ourselves a challenge. By setting the adventure in the Star Wars
universe, it became apparent that much more was needed then just actors and
a storyline. Furthermore, to hide the fact that we were NOT actors and we had
a rather loose storyline, we knew that special effects would carry the story.
Note: We can get away with this. That's because we're in high school.
When you're making a $100 million dollar movie, you need effects, acting,
AND a story. Keep this in mind. :-)
Anyway, we've attempted to chronical the different techniques used to
create the world of "Star Wars : Macbeth." Hopefully you'll gain a greater
insight on how we made these things work and how special effects work in
general. Hope you enjoy it!
Blue Screen
|
One of our first scenes contains the images of Macbeth
and the Imperial Officer discussing matters inside the castle.
(or the Death Star, depending on how you look at it) To create
this scene, we used a techique similar to your local weather
program. We put Bien and Carl, fully costumed, in front of a
"blue screen," essentially a blue carpet hung from end to end
of Bien's bedroom wall. We filmed this with our video camera
and put it in the computer.
|
|
With the Mediastudio software we then selected the color blue and
told the computer to remove it from the video, thus making everything
blue in the scene transparent. (It was important to make sure that
neither of them were wearing blue, or they'd be invisible!) We grabbed
a couple frames from the Death Star scene in Return of the Jedi, inserted
our characters into the picture, and BOOM, we were in the Death Star.
|
This techique was used most significantly during the final
scene, when we attempted to create a conclusion to MACBETH by
integrating them into the throne room scene from "A New Hope."
We were watching the movie, trying to come up with ideas for
our video, when we began to think about how crazy and wild it
would be if we just REPLACED THE WHOLE SCENE. So we did it -
it was quite difficult, but it worked rather well, dispite a
few slight glitches. (such as Princess Leias hair!)
|
Blue-screen is of course a very popular technique in many motion
pictures nowadays. Its biggest drawback is that its very obvious when
its used.. take Air Force on for example - we all know Harrison Ford
wasn't really hanging off that plane. Still its relatively simple and
cheap - which is why it remains popular to this day.
Worst big budget blue screen shot on record : The Nazis and the
blimp in Indiana Jones and the Last Crusade. (what's with Harrison
Ford and blue screen?)
Rotoscoping and Animation
|
Another popular movie techique, although a bit more complex,
involved directly manipulating each and every frame to create
the illusion of something that is not really there. In a way,
this techique is very similar to animation, and has been used
in that medium on many occasions. In fact, the lasers in Star
Wars : "Macbeth" were animated.. essentially little red lines
that moved towards or away from the screen, depending on what
the camera angle was.
|
|
The light saber battles largely used this technique to create the
illusion that the light-sabers were glowing. In fact, our method was
very similar to the original techniques used in the first Star Wars
movie. In "A New Hope", they basically painted (or scratched) on the
individual film negative in order to make the sabers glow. For our
production, we used Adobe Premiere to digitally edit each and every
frame. That's 30 frames per second... ouch. During the real battles,
we used white plastic sticks. We painted over these with red or green
lines, with a couple different layers to acheive transparancy and a
three-dimensional feel. It took a lot of time but the effect worked
out really well and made the fight scenes look really flashy. (which
was why they probably came up with the whole Saber idea in the first
place)
|
The new Star Wars prequels will probably contain a lot of
roto-scoping work. Basically, when blue screen is too limiting,
and there is too much movement to use a matte-shot, the folks at
ILM will have to digitally adjust every frame of film to acheive
the desired effect. What's great about the whole system is that
through computers, we've come up with a way to acheive
photo-realistic animation. Now, it is truely possible to create
realistic, never before seen worlds.. and that's what we're
going to see next May.

Image Mattes
Another technique that was used extensively in the Star Wars trilogy.
Matte Shots involve removing a static portion of the image and replacing
it with something new. For example, the emperor's enterence in Return of
the Jedi. They never built that set. (thank god!) What we saw were about
twenty or so people in the middle of the screen moving around. The rest
of the image was STATIC. Not moving. It was a painting! Matte Artist's
work is highly respected.. imagine having to create a painting that looks
so real that people will mistake it for a real setting... Nevertheless,
the technique added vistas to all three Star Wars movies, and expanded to
scope of the universe in ways that definately payed off to the movie-goer.
In Star Wars : Macbeth, matte shots were used to create the illusion
that the high school was the Death Star! When Rob, Ray and Mike run down
the stairs, the high school windows were removed and replaced with the
emptiness of space. This was relatively simple, and it involved telling
the computer to place an image in front of a certain section of the frame
for a certain period of time. The catch was that we couldn't move the
camera.. or else we'd have to move the matte.
|
Our favorite Matte shot takes place during my soliliquy,
(Luke Skywalker's Lament) As I walk through the room, the
windows behind me are showing a scene from Empire Strikes
back. I continue my whining as if nothing has happened. :-)

Traditional Effects
For all the high tech wizardry involed in producing a movie,
sometimes Ockham's Razor proves corrrect. (come on, didn't you ever
see Contact?) The simplest explanation is often the best one. During
Young Siward's fight with Darth Vader, which we patterned after the
Obi-Wan fight in "A New Hope", we had to make Young Siward dissapear
when Macbeth swung the saber at him. We used a fishing rod and fishing
line to hold up the Siward's robe, and we let the line out when the
saber came through to make it look like Siward had vanished. It looked
pretty good on video, much like the original version in "A New Hope."
Fishing line was also used as "The Force." It made Luke's saber fly
towards him during the final battle. Strangely enough, more people asked
about that simple effect than about how we made those light sabers. Go
figure...
Lighting
|
All good movies MUST have good lighting. Its essential
to the atmosphere of the picture. For our low budget production,
Imperial Officer Carl Erik Fisher doubled as our lighting
technician, and he dutifully flicked the lights on and off as
we ran down the hallways. We did this essentially to make the
scene look a bit more exciting. Kind of like the Death Star was
exploding or something...
|
|
We shot the final battle on the high school stage, right next to the
cafeteria. Here, we could afford an expansive dark background, as well
as some neat colored lights that gave a neat feel to the tension and
dread as Macbeth and Macduff met face to face. We also employed a
full-strength industrial fan in order to spruce up the epic quality of
this scene. Between the wind and the heat, we felt like we were in the
middle of a storm up there. :-)
The Millenium Falcon Escape
The great Act III climax of Star Wars:Macbeth involved our heroes
escaping from the exploding death star wih the Millenium Falcon. This
scene required the use of just about every effect under the sun. :-)
First, our heroes had to run towards the Millenium Falcon as Carl
attempted to shoot them. We used a toy Millenium Falcon (a collectable
now I think!) and we superimposed this image using the bluescreen on top
of the three of us running in the gym.
After we made it inside the Millenium Falcon, we used the blue screen
to superimpose Han Siward, Macduff, and Malcolm in place of where Han, Luke,
and Leia had once been : the interior of the spacecraft. To get the effect
of flying around the gym, we replaced the viewing window with a "fly-by" of
the high school gym (we moved the camera around like it was an airplane).
Conclusion
In essence, the special effects used to create Macbeth are not very
difficult in theory. The trick came in knowing when to use each technique,
and how to create an illusion that looked clean and professional. In this
case, we weren't aiming for realism of course... we'll save that for ILM.
