Academy Award-winning actor Tilda Swinton will narrate Goliath: Playing With Reality, a virtual reality experience directed by Barry Gene Murphy and May Abdalla, set to World Premiere at the 78th Venice International Film Festival on September 1.

Goliath is a 25-minute animated VR experience that—through mind-bending animation—explores the limits of reality, demonstrates the weight of mental illness, and lauds the supportive power of the gaming community.

Tilda Swinton is the voice of Echo, the narrator who guides users through the many realities of Goliath, a man who spent years in isolating mental health institutions but who finds connection in multiplayer games. Combining heartfelt dialogue, mesmerizing visuals and symbolic interactions, the experience sheds an empathetic light on the condition of schizophrenia while taking users through multiple worlds to uncover Goliath’s poignant story.

“Goliath is an exploration of the places we choose to feel safe in, and what it means to experience someone else’s reality. Through the use of VR technology, we immerse users in a world where things aren’t as they seem in an effort to unpack our preconceptions and prejudices around mental health and the shame engendered by psychiatric disorders,” said directors Barry Gene Murphy and May Abdalla. “Tilda brought an understanding and otherworldly gravitas that lifted the character of Echo and the experience out of the ordinary. We hope her collaboration brings new audiences to the medium and with it, a deeper awareness of the subject matter of Goliath.” said Murphy.
