Marvel Studios has kicked off its 31-day social media initiative known as "HelaWeen," named after the villainous Hela, played by Cate Blanchett, in Thor: Ragnarok. For the entire month of October, ending with Halloween/Helaween, Marvel Studios will unveil a new piece of content for Thor: Ragnarok, with this first item being a new poster that gives fans a closer look at Hela and her deer antlers/headdress thing. It remains to be seen if every piece of content unveiled this month will revolve around Hela, but it will surely be a month where we get to see more from this movie than ever before.
