Info on Trevor Howard movie

[Redskinluver]

I am trying to find out more about a 1958 movie "Roots of Heaven" starring Trevor Howard in which he plays an African game warden who spanks a female hunter,played by Juliette Greco,for killing elephants.
Spanking Facts and Research had a little info, not much. Someone posted that she received 12 cane strokes on her bare bottom. That I find hard to believe about a mainstream film in 1958.
Like to know more, if anyone has seen that movie, or if there is a clip somewhere on line.

Thanks!
