Nino has probably the strangest role of his entire career in the bizarre Nazisploitation film
Holocaust parte seconda: i ricordi, i deliri, la vendetta (1978). Originally shown at the Cannes Film Market in 1978 under the title
Subliminal (Una splendida giornata per morire), the film was not screened to the public until in 1980 under the
Holocaust parte seconda title.
From what I can gather, this film is actually made up of footage from two unfinished films: a Nazisploitation movie shot in 1976 and some kind of revenge flick shot in 1978, plus other minor footage spliced in here and there in an attempt (albeit a rather unsuccessful one) to make it all coherent. Gordon Mitchell appears in both the 1976 and 1978 footage, looking
completely different in both.
As for Nino Musco, he has a credited but very minor role as
Alfonso, a former Nazi who is wanted by a ruthless gang of Nazi hunters. After they are unable to hunt him down, they instead murder his son, and when he comes out of hiding to visit his son's grave, they kidnap him. We never get a very good look at him during the scene at the cemetery, though, and I suspect this sequence was actually shot with a double for Nino after the original shoot
We do, however, see the real Nino in a short sequence where he is tortured to death
Only at the end of the scene is it revealed how he was killed: a goat was licking his feet - tickling him to the point of a heart attack!
That's Nino's entire performance, but he still receives a credit in the cast list at the end. I've also no idea when his footage was shot: 1976 or 1978, or possibly at some other time...
