Gordon Jump?
I say that's Gordon Jump inside the plane measuring the hole at the end of the movie.
shareI'm sure it's not. The credits list here is very extensive (including many actors without speaking roles) and he's not on it, nor is the film listed among his own credits.
My vague recollection of the guy is that he didn't look at all like Jump. Next time the movie is on I'll look again for the fun of it but there's no indication whatsoever it was Gordon Jump.
