Scenes From Great Movies on Instagram: "During the underwater training test in Kingsman: The Secret Service (2014), the cast came shockingly close to actually drowning. The scene was filmed in a sealed tank with rising water, and due to a miscommunication on set, the safety divers didn't enter at the right time. Their frantic breaths, panicked eyes, and desperate movements in the final cut aren't acting, they were their real reactions in a genuinely dangerous situation."
