The idea behind "The Phantom Broadcast" is very good...merging the classic story of Cyrano with a modern murder mystery. However, I can pretty much guarantee that folks won't love the end result...and I was left thinking it SHOULD have been a lot better.
Norman Wilder (Ralph Forbes) has a gorgeous voice and his songs are adored by millions over the radio. But what few realize is that Wilder is ashamed of his severely hunchbacked body and uses a proxy to pretend to sing his tunes. So, he plays the piano as his dummy moves his lips and pretends to sing. Sadly, however, this 'dummy' is incredibly foolish and soon begins to believe that he's god's gift to women and he even begins mistreating Norman...even though Norman is his meal ticket.
In addition to treating Norman like dirt, this puppet uses his fame to chase women...lots and lots of them. And it's because of this that he eventually gets himself killed. At this point, the story goes off the rails, so to speak. What had been a very good story suddenly began making less and less sense...leading to a finale much like that in "Cyrano de Bergerac".
With a slight re-write, this Monogram film could have actually been very good and quite memorable. But the behaviors of Norman AFTER his proxy was killed...well they really didn't make a ton of sense. Worth seeing as a time-passer and not much more.
