Rahul Yadav on Instagram: "Filmmakers don’t actually risk actors’ lives to shoot underwater scenes — they build the ocean on land. Most “deep-sea” shots happen inside massive water tanks with controlled lighting, filtered water, safety divers, and hidden rigs that keep actors stable while the camera floats around them. Add a little CGI for bubbles, depth, and color… and suddenly it looks like they’re 50 feet under. It’s movie magic built on engineering, not danger. @rahul_razz_yadav #filmmaking
