Nothing makes actors miserable like running around in the desert.
Screen Rant collected 20 of the best scenes that made their actors deeply uncomfortable, which span from the purely physical (running at top speed in the heat of Abu Dhabi in The Force Awakens) to the psychological (everything inflicted on Shelley Duvall in The Shining) to the downright disgusting (hiding in barrels full of real fish in the second Hobbit movie).
While some of these feats — like literally everything Leonardo DiCaprio did to finally win his Oscar for The Revenant — were well publicized, it will give you a renewed appreciation for just how hard actors work to get the perfect take.
