British filmmaker of Indian origin Asif Kapadia, who has directed a documentary on singer Amy Winehouse, says she did not like her popular song "Rehab" and also neevr thought it would be a hit.
Kapadia, said the song was a "cry for help", reported E! Online.
"I don't think she liked the song. It's dark and it's a cry for help. I think she was surprised it became a hit. The trouble was already there, but that's when it really kicked off," the "Senna" director said.
"That song became, I think, the thing that she hated. People wanted her to sing it and she's singing it with a drink in her hand. It's a cry for help. Every time she says, 'No,' she's saying, 'Yes.'"
Winehouse, who wrote 'Rehab' about her own life, died of alcohol poisoning on 23 July 2011, aged 27.
"Amy" will release worldwide on July 10.
