This masterclass, led by renowned film editor Anastasi Rinos, delves into the art of editing in the works of acclaimed director Bigas Luna. Focusing on key films such as 'Bilbao', 'Caniche', and 'Reborn', Rinos provides a thorough analysis of editing as a narrative tool. The session illustrates how elements like rhythm, ellipsis, and the intricate relationship between image, sound, and silence contribute to creating psychologically charged atmospheres in Luna's films. As an essential figure in Spanish cinema since the late 1970s, Rinos's insights reveal the collaborative nature of editing and directing, making this an invaluable opportunity to understand the editor's role as an invisible creator within the filmmaking process.
