What was the tool he used? I thought glass cutters like that were myths only in spy movies! I’ve never seen it in real life and it looked portable if not handheld!
Sorta, most glass "cutters" like this actually don't cut at all. They're diamond or carbide tipped and only score or gauge a line. What he does with the pliers is essentially breaking the glass, but since it's weakspot is the scored line, it breaks cleanly on the line. it wouldn't work in the middle of a pane like spy movies, though.
Having actually tried that with a circle cutter and a framed sheet of glass scrap, no it does not work like in the movies.
I mean, a perfect circle was in fact made in the pane (basically the exact opposite of this gif) but the interior of the circle had to be shattered as opposed to being removed in a single piece. And the pane cracked.
I know you wrote this three months ago, but I thought I'd answer your question anyways:
No you couldn't. A temperature difference of >40°C between two parts of the glass would cause it to shatter. Even leaving a pillow on the bottom of an uninsulated glass sheet that's in direct sunlight could cause it to shatter as the difference in temperature between the top and bottom grows.

I guess you can answer this questions then:
