Saltburn star Barry Keoghan has said he doesn't want his background to be a "pity story", saying he hopes it can inspire other children with a similar upbringing.
The actor and his brother spent most of their childhood in foster care after their mother, who struggled with drug addiction, became unable to care for them.
"I speak about it to let younger kids know no matter where you come from, you can always achieve what you put your mind to" he said.
Keoghan addressed rumours and criticised internet trolls for making assumptions about his family life on The Louis Theroux Podcast.
Asked about his mother's heroin addiction, the actor said it "caught her" as well as his uncle and father.
"She was just unable to look after us. My father wasn't there and so we got taken into care.
"That kind of thing still haunts me" he said, "you don't forget waiting on the social worker steps and waiting for a new family to come and play with you.
