There are many OFF moments, when not much is happening during a filming… andthat can last for hours. This is when everyone types away on their smartphones between scenes.
I love surfing on the blog of The Jalous Curator, a girl who posts really amazing inspirations.
Otherwise: I always put together a playlist in the image of the character I am acting out. For example, in Le Secret d’Elise, it begins on an uplifting tune (she is pregnant, in a very happy state of mind), then things become darker and darker.
