Filmmaker Wolfgang Thaler gets up close and personal
with honeybees during the making of the NOVA film "Tales From the Hive."
The Making of
If you watched the NOVA program "Tales From the Hive," you're probably wondering how
the filmmakers secured some of that astonishing footage of honeybees. How did they
get closeups of bees in flight? Of a queen mating on the wing? Of the inside of a
brood cell deep within a hive? In this engaging interview, enhanced by images taken
during the making of the film, cinematographer Wolfgang Thaler reveals the tricks
he and his team employed to capture the most intimate honeybee behavior.
NOVA: How did you get those close-up shots of a bee in flight?
Thaler: During the preparation phase, the thought of trying to get those kinds
of pictures gave me a big headache, because it was clear that we had to shoot bees in
flight—first to experience the flight of the bee emotionally, and secondly, to do
justice to the standard set forth by the international nature film genre.
After much preparation, Thaler succeeded in
getting sequences like this one, in which it almost appears as if he's hanging
off the hind feet of a flying honeybee.
I experimented with many different lenses without any satisfactory results. Then
I heard of a professor at the Pathological University Vienna, in Austria, who
achieved great results with endoscopic optics, which are being used in medicine.
I visited him several times to learn more about these "wonder lenses."
The next step was to find out how I could fly with the bees, because they are
fast. I told myself, if I can't fly with the bee, then the bee has to fly with me—that is, with the camera, directly in front of the lens. It was like the work at a
clockmaker's. We used a pair of tiny tweezers to form a wafer-thin wire. We then
tied the bee up with this—very carefully, because we did not want to harm the
bee, and we wanted to make sure it had the freedom to move its wings. A special
kind of arrangement enabled us to fix the wire to the camera.
The bees didn't volunteer for this procedure, and the hardest part was to avoid
getting stung. Before the flight, the bee got a sip of honey from a pipette, and
after successfully landing, it was set free again. That's how I could film the bees
in flight from the front, back, and side. All I had to do was move with the camera
and the flying bee through the landscape and jump from flower to flower. This
learning process took more than a year, however. This procedure was even harder
with the queen, because she is easily injured and not as robust as a worker bee.
Also there is only one queen per bee population.
One of the most extraordinary scenes in the film is this of a drone mating in mid-flight with a queen.
NOVA: How did you get the shot from the side of the flying queen bee mating with a drone?
Thaler: The mating of the queen takes place somewhere out in nature, in flight,
at places where drones assemble and wait everyday for a queen to come by. Such a place
could be anywhere, in the woods, a meadow, or even a football stadium. Some beekeepers
know these places. To date, scientists have not been able to figure out why drones
assemble only in certain places or how the queens locate these spots. We had to
find such a place that was flat enough to build a tower, because the mating takes
place at a height of about 65 to 100 feet.
We built a tower about 26 feet high and mounted the camera at the end of a
six-and-a-half-foot-long extension. With this we were able to set the camera
into a 360-degree rotation. (The queen has to be flying to mate.) We "tied" the
queen in front of the camera, then we had to lure the drones from their altitude of
100 feet or so down to the level of our queen. For this purpose, we filled a weather
balloon with helium, tied queens in a cage underneath that balloon, and let it rise.
The idea was to draw the drones down with the queens' pheromones.
Since mating takes place high off the ground, the film crew built a temporary tower to capture the elusive moment on film.
Amazingly, it worked on the very first day. I don't know how or why; perhaps I'm
lucky. On the other hand, we never succeeded in repeating this scene over the
following days. When the queen finally moved her wings, the drones were not
interested; when she flew and the drones felt like it, the wind was too
strong. If I had known how impossible it would be to film the scene while
I was writing the script, I would have cut out the queen's mating flight.
NOVA: How long did it take to get the toughest, most valued shots?
Thaler: It seems absurd, but the obviously easiest shots posed the greatest
difficulties. For example, it was almost impossible to get the drones in front of
the camera—simple things like having them crawl through the picture from left
to right. They were far too shy, and because of their large eyes, the camera and
the light must have posed a threat. The worker bees were not much disturbed by
light and camera; when they had a job to do in the hive, they accomplished it.
From the beginning of the project, the biggest challenge was to shoot the
inside of the hive without interrupting the natural behavior of the bees.
With every day of the shoot, we became richer in experience, and so I saved myself
the most difficult shots for the end. These included the queen laying her eggs
(filmed from the inside of the honey cell), the storage of pollen, and the
feeding of the larva with royal jelly. Again we had a lucky day, because
queens are the shyest of all bees, especially young queens. As soon as something
disrupts their environment, they stop their natural behavior and hide among
thousands of bees.
NOVA: What are you working on now?
Thaler: In February 2000, we will begin shooting a film on salt. Salt was
once called "the white gold," because it was the engine of many civilizations.
Most people today take this crystal for granted, but there are still places in the
world where people have to wring salt from nature, under the toughest conditions.
As my next project, I'd love to do a film about ants, to enter their fascinating
world. In cinematographic terms, this will be a big challenge for me, because these
insects are very small and fast, and they live mostly in inaccessible places.
