Stage actress-director Olivia Yan Wing-pui looks frazzled. 'Sorry, sorry,' she says, apologising profusely for her lateness. 'I came straight from a rehearsal ... it was wrenching.'
The scene the 42-year-old has been working on revolves around a couple approaching the end of their relationship. 'The woman one day finds herself defying gravity, just like those floating figures in [Marc] Chagall's paintings,' says Yan.
'Each day she elevates a little higher and the man has to tie her down with a piece of rock. The terrible thing is that the woman begins to enjoy the sensation of floating and freedom. In the end, the man decides to release her into the sky. The story is about letting go.'
This emotionally intense vignette comes from Yan's latest show, Viva Odyssey, a sci-fi fantasy that looks at human existence and asks: 'Why are we here? What is life?'
The artist says she's always been obsessed with these philosophical questions; she used to discuss them with her bemused school friends.
'This obsession comes from my love for life and fear of death. I love listening to the sound of my daughter's heartbeats and watching people breathe,' says the mother of one. 'I'm constantly exploring the meaning of our existence.'
