Yesterday, Thor: Ragnarok director Taika Waititi shared one final set video through Facebook Live on the last day of production. Shortly thereafter, star Chris Hemsworth shared a final photo from the set, showing off a new Thor costume in this image with director Taika Waititi. Aside from offering one last look at the star and the director on set, Chris Hemsworth also used the image to highlight a worthy cause.

Chris Hemsworth shared the image on Instagram yesterday, with him and Taika Waititi holding up a sign that reads "We stand with Standing Rock #WaterIsLife #NoDAPL #mniwiconi." The star and filmmaker were showing their support for the the growing protest against the Dakota Access Pipeline, which, if it is built, would cut through the Standing Rock Indian Reservation in South Dakota and potentially pollute the Sioux tribe's water supply. Here's what Chris Hemsworth had to say on Instagram below, including an apology for a costume he wore for a theme party he attended on New Year's Eve.

"Standing with those who are fighting to protect their sacred land and water. I would also like to take this opportunity to raise something that has been bothering me for sometime. Last New Year's Eve I was at a "Lone Ranger" themed party where some of us, myself included, wore the traditional dress of First Nations people. I was stupidly unaware of the offence this may have caused and the sensitivity around this issue. I sincerely and unreservedly apologise to all First Nations people for this thoughtless action. I now appreciate that there is a great need for a deeper understanding of the complex and extensive issues facing indigenous communities. I hope that in highlighting my own ignorance I can help in some small way."

Marvel still hasn't released any official plot details at this time, but there have been no shortage of rumors surfacing throughout the production. One of the most prominent rumors revealed that Thor will be banished from Asgard after his nefarious brother teams up with the new villain, Hela (Cate Blanchett), who destroys his mighty hammer Mjolnir. This reportedly sends Thor on a quest that brings his to a gladiator planet, where he is forced to face the current champion, Hulk (Mark Ruffalo). There have been rumors that certain aspects of the iconic Planet Hulk comic will be utilized for this story, although it isn't a direct adaptation of that beloved comic.

Returning Thor franchise characters also include Tom Hiddleston (Loki), Anthony Hopkins (Odin) and Idris Elba (Heimdall). This sequel will also bring new cast members into the fold such as Tessa Thompson (Valkyrie), Cate Blanchett (Hela), Karl Urban (Skurge) and Jeff Goldblum (The Grandmaster). Take a look at what could be the final photo from the set of Thor: Ragnarok, which is set for release on November 3, 2017.
