On the surface, “The Odyssey,” an adaptation of Homer’s epic saga of the same name that features an all-star cast led by Matt Damon as Odysseus, is far more commercial. Forskellen? “Oppenheimer” cost around $100 million to make. By no means a small budget but not huge for a Christopher Nolan motion picture. “The Odyssey,” however, carries a reported $250 million price tag (not accounting for marketing), which makes it one of the most expensive R-rated movies ever made.
