art healer on Instagram: "Most ocean scenes in movies are filmed using greenscreens and water tanks for the actors, while the actual ocean, waves, and storms are created with CGI. Close-up actor shots are combined with digital oceans in post-production, with lighting and reflections matched to make everything look realistic. This allows filmmakers to safely and fully control the environment while still producing stunning ocean visuals."

CLIPS on Instagram: "🥊 Interesting fact: In Fight (2012), the actors performed most of their own fight scenes with minimal CGI. Choreographers worked closely with the cast to make each punch and movement look realistic, giving the underground fighting sequences a raw and intense feel on screen."
