I'll Never Know

I don't "blog" anymore, but I do mark it down whenever I read a book with an owl in it, because who else is going to bother? So Megan and I are reading a book about the making of the film GIANT, and director George Stevens refers to watching the dailies as "the owl show." Am I sure exactly what he means by that? Not 100%. Do I know whether it is an old show biz expression or just something that popped out of the mouth of George Stevens? Truth be told, I do not. Am I going to go to the trouble of looking it up? Nope.
