Gerald's Game

I recently watched "Gerald's Game" and the scene with the moonlight man just blew me away! Does anyone know how this creepy scene was created and what special techniques were used to achieve such a terrifying effect?

Hi. I'm a big fan of this work! I think it's brilliant how director Mike Flanagan used minimalistic techniques to heighten the viewer's fear. For example, the scenes with Moonlight man are built on psychological tension and the play of light and shadows, as well as interesting camera angles. Read the full story about working on the movie and why it became a cult movie.

I wonder how relevant this is. I haven't played Witcher for a long time.
