From the Warner Bros. 2020 movie, "Tenet", directed by Christopher Nolan, and starring John David Washington, Robert Pattinson, Elizabeth Debicki, Aaron Taylor-Johnson and Kenneth Branagh, costume designer Krista Guggia put these items together. A rare screen used prop, helmet and mask from the final battle scene set in "Stalsk 12", Two strike teams converge on the zone to recover the 3 components known as the "Algorithm". Red team enters the battle going forward in time and Blue team is in the "time inversion" aka they are traveling through time in reverse.
The item you are bidding on is configured as belonging to the BLUE team (Helmet and Mask combo). The BLUE team has no external filter, but has a rubber piece inside the mask that covers the nose and mouth (you can see this in the movie stills) and an air line that leads to special mini oxygen tanks, which is vital for anyone who is temporally inverted. This item does not include the airline or hose attachment. Air hose not included, but I will be selling some of the tactical vests that have the hose attached to them in other auctions.
The helmet appears to be a version of a flight deck crew helmet. I believe the cloth portion of the helmet may have some subtle additional coloration to it to give it the appearance of age. There is also some real dust and dirt on there, presumably from the many weeks of shooting out at Eagle Mountain, where the final battle was filmed. The style of ear protection varied amongst the costumes, so this small detail may or may not match the "hero" version you see the main stars wearing, but rest assured they are all from the same lot.
The Mask is model CM-6F1, manufactured by Mira Safety. They sell a version of this mask for retail customers. You should expect to see some surface scratches on this item, there was a lot of stunt work done out at the filming site. This is a real gas mask, however the prop department has modified them, so you may need to replace a few parts from the manufacturer to make them work properly.
The first four photos are of the actual item you are bidding on. Sorry no COA. Be the hit of your next halloween party, comic-con, paintball war or temporal pincer, I haven't seen any other sellers with this item!
(Helmet is Size Large)
Thanks for your interest - happy bidding!
