the “river of blood” is a common misdirection

technique used in advertisements.  in a television

commercial, for instance, while describing the

possible negative side-effects of a given brand

of cereal it is common for a river of blood to

be shown flowing rapidly on screen.  i read

once that each commercial’s “river of blood”

is actually a unique part of an entire film of

the same name.  there was a super bowl ad

this year where a “river of blood” clip was

shown for an entire 40 second span.  this

clip was not part of a commercial and there

was no sound.  slowed down, the last few

frames show an object entering from the

left side of the screen moving against the

current.  i never kept up with sports but

i have always been interested in marketing.

i don’t know what happens when you splice

all 5 minutes of footage together.
