Sophia Petrovna, sorry

[Mansour, L. DR DFL]

Worm of commercial interest bites Stalin's tail?  Or is there another
explanation?  My query concerning availability of the film version of Lydia
Chukovskaia's "Sophia Petrovna" elicited a number of requests to post
results... but only one lead, which unfortunately didn't pan out.
Thanks to those who offered help.  And let's keep looking.
