A sister’s last hope to save her brother from addiction – David Vincent Smith’s He Ain’t Heavy is a triumphant debut

Bonsai Fims

So, on we go
His welfare is of my concern
No burden is he to bear
We’ll get there
For I know
He would not encumber me
He ain’t heavy, he’s my brother
– He Ain’t Heavy, He’s My Brother by The Hollies

Writer–Director David Vincent Smith’s reference to The Hollies’ 1969 hit as the title for his new film is not without irony.
