Something my wife pointed out last night when we watched the BR extended The Cage: Spock's limp. It is plainly noticed after they first beam down to the planet surface and walk toward and touch the musical plants. What's the cause for the limp? I assume it was acquired after visiting and fighting on Rigel 7.
The November 20th, 1964 Final Draft script for "The Cage" (from back in that very narrow window of time when the Captain wasn't called "April" anymore and he wasn't yet called "Pike"--he was "James Winter") has some script direction that clarifies what's going on:
From Scene 4:
Ship's Science Officer, MISTER SPOCK, nursing a foot injury, limps onto scene to stand beside Winter, watching the viewing
screen, too. We notice Winter has thrown a concerned look
toward the injured foot, the Science Officer in turn
minimizing the limp as if trying to show there is no reason
for concern.
From Scene 5:
At the navigation position is JOSE TYLER. He's managing his
controls and instruments fairly well despite a left forearm
bandaged down to his palm....
Winter seems almost more concerned with the young
Navigator's injury, watching as Jose turns back to his
hooded screen, forcing his injured arm to do its full share
of work at the complex controls....
From Scene 6:
Spock whirls, limps hurriedly for his Science Officer's
Station, the huge central computer, begins to request
for information on the signal being received.
From Scene 16:
WINTER
Equip a landing party of six.
Ship's Doctor, geologist, Chief
Garison...
Mister Spock, Jose, and Number One wait expectantly as Winter looks in their direction....
WINTER
All right. Mister Spock, Mister
Tyler. See there's a fresh
dressing on your wounds.
In addition to Mister Spock walking with a limp:
...the two other injuries we see from the recent fight on Rigel VII are Jose Tyler (who has a bandaged right hand), and the unnamed (Fisher?) geologist who has a bandage on the left side of his neck. You can see them as they beam down to Talos IV:
So, we see that Spock's and Tyler's injuries were required by the script. The geologist's neck injury wasn't scripted, but they bandaged him anyway. Also, they bandaged Tyler's right hand instead of his left hand as scripted, presumably because as he sits at Navigation, his right hand is downstage and is better seen by the camera. Lastly, of course, Winter's/Pike's "put on a fresh dressing" line was simply changed to "do you feel up to it?"
