The behind the scenes clips I watched from Thor Ragnarok were so interesting. Marvel movies in general are so detailed everything is perfect and the same goes for this movie. Some of the set producers talked about how the set was made and how they went about some of the props such as the throne and Sakaar (the city where some of the movie is set it).

When talking about making a thorne you wouldn't think it would be so hard but on the floor of the throne alone they used ten coats of paint and polish. While making the city of Sakaar they did experiments on how certain metals age so they the whole town can go from vibrant primary colors to a corroded city that's not longer in its prime.
