Now!
Look at the extremely close respective positions of
Mr Lovelady in Wiegman and the
lady in white in Darnell.

Can you see a 'shadow' down the lady in white due to the western column? Nope!
Yet we do see a 'shadow' down the right side of Mr Lovelady.
Did the sun dart east between the two films??
Ain't no shadow, folks! So what is it, and why is it there?
