The film used will have an impact, but your use of light will make the look more than the choice of emulsion will make the look. Your choice of aperture and shutter speed will also matter. Candles are a constantly moving source of light, so shutter speed does matter. The film (my favorite movie, BTW) was shot with only period-correct lighting; no electric lights. I assume you are talking about the look of the indoor scenes. I would go ahead and light a gross or so of candles, and have at it with some daylight films like the two you are already considering, or a more flat neg film like Pro 160S/Portra 160NC. Try some with various degrees of cool filtration (82 filters), and possibly the full-on color conversion you get from an 80-series filter, which will still make for a warm tone in candle light. When shooting your negs, overexpose for two reasons: 1. So the blue layer gets enough exposure to let you change color balance as desired (if shooting without filters), and 2. to lower the over all contrast of the shot. If you are shooting transparencies, you can mess with pushing and pulling more than you can with negs; pulling especially. For your lens, whatever it is, I'd use it wide open to soften things as much as possible. No need to rush out and buy an f/1.2 lens. Just use whatever you have wide open and see what happens.
