Collins has gone on the record before saying she spent years controlling her eating habits and abusing laxatives for nearly a decade without her friends or father (Phil Collins) knowing about it.
It’s worth mentioning as well that To The Bone star Lily Collins has also talked about her struggles with an eating disorder through numerous outlets, so it would appear many people educated on the subject matter had a hand in this film.
From the sound of it, it seems as though some of the scenes Collins is acting in the trailer are portions of her life that she may have actually lived, which could provide further legitimacy from those opposed to its airing.
