During our two-day interim, I was meandering through some more Season Three episodes, and the editing for the introduction of "The Much Heralded Helmet of Sir Gawain" caught my attention. (Photos courtesy video from youtube.com posted by OlmecFan25)
The first time photo (upper left, at 0:54) comes right after Olmec announces the artifact for the day, and Kirk replies, "Oh! The Much Heralded Helmet of Sir Gawain!" Then at 0:55 (lower left), that first camera cuts and a second camera does a sweep of the moat before the teams get introduced (when Kirk says, "Well one of our teams will have a chance to retrieve the Helmet!"). Then, right before each teams gets their face time, a new camera angle shows Kirk saying, "Will it be the Red Jaguars?" at 0:56 (upper right). This is where it gets interesting... as you can see in the photo series, the moat obstacle changes from the swinging bridge to the rope and cargo net. When they introduce the teams and then go back to Kirk saying, "First they're gonna have to cross the moat, and here's how they'll have to do it today," at 1:16 (lower right), the moat changes back to having the swinging bridge.
Hmmmm..... very interesting editing job, if I do say so myself.
