Don't think he sounded Hungarian. I had a girlfriend of Hungarian descent when I was young. She was born in Holland (and therefore spoke Dutch with a Dutch accent), but her parents were born overthere and spoke Dutch with a strong (I suppose) Hungarian accent. It didn't sound like any other accent at all (not like Russians or some Asians speaking Dutch), and not like Palance in Companeros. There's some homosexual symbolism in Companeros, and I think Palance tries to sound a bit homosexual.
