In the annals of filmmaking history, few scenes are as iconic as the infamous shower sequence in Alfred Hitchcock's Psycho. A cinematic masterwork in its own right, the scene is almost flawless, except for a minor mistake that only those with a keen eye (or a background in mortuary science) are likely to spot. As Janet Leigh's lifeless body lies crumpled on the floor, her pupils are noticeably contracted instead of dilated, as they should be in a state of death. Being the perfectionist that he was, Hitchcock took note of the error and consulted with a team of ophthalmologists, who advised him to use belladonna eye drops when portraying deceased victims. The fact that Hitchcock went to such lengths to rectify this mistake (if you really want to call it that) only underscores his commitment to his craft and the enduring legacy of this cinematic masterpiece.

Full Metal Jacket - R. Lee Ermey's Entire Performance

Full Metal Jacket, a searing exposé on the ravages of war, continues to captivate audiences with its unflinching portrayal of the horrors of combat. Despite being nominated for an Academy Award for Best Writing, it's worth noting that the film's most memorable character was never even supposed to have lines. R. Lee Ermey was originally brought on as a technical advisor, drawing on his real-life experience as a Parris Island Marine drill instructor to coach the actors. However, when director Stanley Kubrick saw Ermey in action, he realized that the man himself was the embodiment of the character he had in mind: the tough-talking, no-nonsense Gunnery Sergeant Hartman.

Rather than relying on scripted lines, Kubrick gave Ermey free rein to improvise as he saw fit, capturing the essence of his drill instructor persona on film. Over multiple takes Ermey and Kubrick crafted a tour de force performance that stands as one of the most iconic in cinematic history. And for those who might claim that Kubrick was a rigid, controlling director, the story of how Ermey's natural talent was harnessed for the film proves that even the greatest auteurs know when to let their actors take the reins.
