Red smear in the credits
No, I'm not talking about the Hollywood blacklist....
But in the opening credits of this film, when the screenplay credit for Harry Clork (this is a real name?) is shown, the credits underneath it have all been eviscerated -- it's just a big, red smear obliterating whatever or whoever was listed there. (The credits' lettering is all in red.)
I'm guessing that what's been smeared out (and "smeared" is the right word -- like someone wiped paint or nail polish all over wet ink) are the names of the original writers of the musical on which this film is based, No, No Nanette; or possibly, since that show had already been filmed twice before (in 1930 and 1940), it's the credit of someone connected with an earlier screen adaptation.
Then again, it may be something/someone else altogether.
I'd love to know two things: first, what was originally written there where it's now illegible; and second, why (and when) was this done? Is it a rights issue? (I doubt it.) Might it have been a blacklisting issue that arose the following year when the blacklist exploded in its full fury -- that somebody's name suddenly had to be removed? Or was it something else?
This is just a very weird thing to see, and with no ready explanation as to what was there or why it was erased. Not to mention that it was so clumsily done. This huge red smear, among other things, looks really, really ugly.
