  Carice van Houten portrays the titular character of the episode, the Red Woman Melisandre.
  "The Red Woman" was directed by Jeremy Podeswa. Podeswa previously directed the fifth season episodes "Kill the Boy" and "Unbowed, Unbent, Unbroken", the latter of which received a Primetime Emmy Award nomination for Outstanding Directing for a Drama Series. The budget for the sixth season increased compared to the previous seasons as each episode had an average cost of over $10 million, totaling approximately $100 million for the full season, setting a new high for the series.
  For the closing reveal involving Melisandre, the director of the episode stated that a similar technique to the body double of Cersei Lannister in "Mother's Mercy" was used, with Carice van Houten wearing prosthetic makeup for the face that was then transposed onto the real body of an old woman. Podeswa stated, "The idea is there's an indefinite indeterminate quality that she could be ancient. We were limited by choosing to use a real person rather than a complete  creation. Because what does a 400-year-old person look like? We don't know. So if you try to create that, then you're creating something that looks beyond our known reality. Here you feel like she's very old without putting a number on it."
