Observations: The Immunity Syndrome

Thanks to James C, Thomas and others.

The Immunity Syndrome

There are about 14 people in the landing party. There are two Eagles, but Eagle 4 has no passenger seating, only boxes. Eagle 1 has a computer on one side, so only 4 seats. There may be two seats in the rear compartment (as used by the guards in Testament Of Arkadia). So Eagle 4 could have up to 4 seats (including pilots), and Eagle 1 would have 8- leaving 2 people sitting on the floor. Thanks to John Day.

In these frame, the stuntmen's faces are visible.

Initially Tony wears his normal uniform tunic, which has two horizontal red lines and a seam across the chest. After he sees the alien, he is in a different tunic, with three horizontal red lines and no seam (a converted Year 1 top). Thanks to Fergus.

The Immunity Syndrome Space Warp

The scans of the Maya creature from Space Warp can just be seen.

The Immunity Syndrome

The fragment of material that Koenig finds is remarkably square, not like the ragged tears in Tony's uniform.

The Immunity Syndrome

Tony falls down a gully. At the top of this picture, beyond the rocks, a red ladder or frame and a wall can be seen - the studio wall.

The Immunity Syndrome

When Tony fires at Koenig the second time, the sound is slightly earlier than the laser effect and explosion.

The Immunity Syndrome The Immunity Syndrome

After the fight with Koenig, Tony is covered in dirt. When Spencer inspects him, not only has his face been cleaned, he wears a fresh, clean uniform.

The Eagle cockpit is equipped with the space warp detector (from Space Warp). It also has the nuclear bomb controller from Space Brain.

The operator of the thermal lance dies in this episode (actor Harry Fielder; he was the guard named George in Seance Spectre). He is resurrected in the next episode, The Dorcons, as a medic.

Abruptly, people start holding their commlocks in a different way than normal. It turns out this is prudent. Incidentally, this and The Rules Of Luton are the only two Year Two episodes in which close-ups of the commlock screen are shown.

After the explosion, smoke rises behind Alan as he says "We're holding." We cut to a wide shot of the command module, and the smoke has disappeared. Thanks to Simon.

The Immunity Syndrome

Alan gives a very obvious sideways jerk to the control lever to make it break.

The Immunity Syndrome

The top of the sky backdrop can be seen top right (thanks to James. C).
Note that the dead Alphan who they had been examining a few scenes earlier has gone.
This is the only episode where women in an Alphan landing party wear skirts. Thanks to Terry Shewmaker.

The Immunity Syndrome

One distant shot of Eagle 4 shows it without the lab pod.

The Immunity Syndrome

This shot also shows a transporter pod, although it is not recognisable from this angle. It's actually a shot taken from Devil's Planet. The previous shot of the Eagle showed it just above the trees, but the Eagle is much higher here.

The Immunity Syndrome

Two brief shots of Koenig during the crash are reversed left for right. Note his badges are on the wrong side, and the Eagle "1" is reversed. They seem to be out-takes from the crash scene in Devil's Planet. Thanks to James. C

The Immunity Syndrome

During the cabin fire Koenig says "I'll take over." So presumably Koenig was at the helm during the crash, apart from the moments when he was using the fire extinguisher. We see one brief shot of Alan at the controls. Afterwards when Koenig says "Some landing.", Alan says "Yeah. I have to admit it wasn't one of my best." Thanks to Martin Daoust and Todd Keys.

The Immunity Syndrome

As Koenig is carried from the Eagle crash, Alibe stumbles briefly.

The Immunity Syndrome

"Three more of our party have died, and the condition of Chief Security Officer Verdeschi remains grave." Koenig may not have much time, but his comments are not very sensitive. Who died? Listening on Alpha, the staff have no idea if it's Alan or Alive or Spencer who have died. If we don't know their names, surely they have friends on Alpha, maybe family. The assumption is that these are people who don't matter, who had no names and can be casually killed off. Thanks to Richard Totis.

The Immunity Syndrome

"It would be a one way trip, Maya." Moonbase Alpha will lose the last two of it's senior command team- who is left in charge? Fraser? The two most senior medical staff will be gone. Thanks to Richard Totis.

The Immunity Syndrome

The glider-Eagle is docked to starboard, but they enter the portside.

The Immunity Syndrome The Immunity Syndrome

The ladder is shown "forward" of the passenger pod's port and starboard access doors. The access "tube" is clearly "aft" of the pod's access doors. Thanks to Martin Daoust.

The Immunity Syndrome The Immunity Syndrome

There are subtle differences between the model glider and full sized set. The full sized glider has side wings immediately under the cockpit windows, and they are strongly curved. The model glider side wings are further forward and flat. There is a black "O" and a white triangle outline behind the wing on the studio set, but they are not present on the model.

The Immunity Syndrome The Immunity Syndrome

In the glider, Maya's helmet has the air hose connected. Helena's helmet has no air cable. Thanks to Simon. The neck ring is painted white, rather than silver, to indicate they have replaced the "metal seals on the spacesuits".

The Immunity Syndrome

Although corrosion causes the commlocks to explode and Eagles to disintegrate, it doesn't affect stun guns, or the buckles and zippers on Alphan uniforms. The alien communications device presumably does not contain metal parts.

The Immunity Syndrome

The helmet ear pods are very reflective. Fortunately, when Koenig turns it around the edge of the set or the crew are not obvious in reflection, although the boom mike can be seen.

The Immunity Syndrome

The darker edge of the set and studio lights are more visible in the forest set. When Koenig takes off his helmet in front of the alien, we can see the reflections of the studio roof, a light and a crew-member in a red top.
