The character "Boot" wears the iron mask in season 02 of SEE. The production notes for the project were that the front had to be restrictive in a "Man in the Iron Mask" type of way and made from found or salvaged parts. The technology was limited to rivets and binding pieces together. No welding technology was available. The actor also had to be able to get in and out of the mask, with relative ease, in between takes. The actor's ability to breathe and act with limited restriction was also carefully considered.
