One outdoor shot clearly shows the Minnow wrecked on the beach. But the Minnow had been completely destroyed in Goodbye Island (1964).
Ginger is posing as a Bali dancer so Dubov can paint her likeness. But she's facing us; her back is what Dubov sees.
Dubov has been on the island for 10 years without encountering Wrongway Feldman or the Jungle Boy who were there at the same time.
Not only was there no material on the island to use for art canvas, a raft made of paintings would not be seaworthy.
Ginger makes the unfortunate cultural mistake of assuming that a belly dancer is a kind of stripper. Someone in show business should know better.
