@Foofie,
I didn't see that tv-production, so I can't give you an answer.
The - in Germany - so-called "Nacht der langen Messer" ('night of the long knives'), had altogether about 200 victims, nearly all of the SA top men, and some dozens of clergymen and (political) opportunists - the latter had nothing to do with the SA nor were homosexual men.
[Otherwise, in English "The Night of the Long Knives" is the name Geoffrey of Monmouth gave to the slaughter of British chieftains by the Jutes, Angles and Saxons on the Salisbury Plain in ca. 460.]
