Norman said he got one cameraman to film the rub-out. But the chase scene is filmed from various angles: we see Buddy and Norman running at us, there are overhead shots, there are close-ups. It was obviously filmed by 3-4 cameramen. But then, this is an intentional goof. As if to show they know one person couldn't film all this, Junior even comments how "Hitchcockian" the film looks.
