The father of deeply troubled singer Amy Winehouse said a recent film about her life didn't showcase her 'sense of fun'.
He paid tribute to his daughter as a "wonderful singer" and a "great human being" at a recent star-studded gala for her foundation.
Producer and singer Mark Ronson was named patron of the Amy Winehouse Foundation and attended the glittering event.
Speaking from the red carpet at The Savoy hotel in central London, Mitch Winehouse said he hoped the charity would form part of his daughter's story.
"I hope this is her legacy - obviously her music legacy will look after itself. She was a wonderful singer and a great songwriter as well as being a great human being."
The foundation was set up to combat drug and alcohol abuse among young people.
Amy died in 2011, aged 27 after a long-publicised battle with drink and drugs.
Asked what he thought his daughter would make of the charity set up in her name, her father joked: "If she wasn't pleased with what we were doing there would be a smoking crater here with a lightning bolt."
He also spoke of the "deep friendship" Winehouse had with friend and collaborator Ronson.
"(They) made musical history - and their relationship was a deep and loving relationship.
"I don't know how they ever managed to get any work done because they were just laughing the whole time.
"That's what people just don't understand, they saw that film that came out a few months ago - which to me is abhorrent anyway - there is no sense of the fun of Amy.
That was how she got through her problems - by laughing."
Mr Winehouse hit out at the recent film Amy, directed by Asif Kapadia, which he said overlooked the essence of his daughter and the generous work she did.
"We had to see it unfortunately. It was not good, but we move on. We can't dwell too much on it because we have work to do."
He appeared to confirm rumours about the potential release of his own movie, showing another side to the Rehab singer.
"It is not going to be a revenge attack on Asif Kapadia, we are looking to do something positive and to talk about some of the positive things in Amy's life like the foundation, all of Amy's wonderful friends who were ignored in the film, and the other creative work Amy did.
"Everyone had heard that rubbish. Let's hear something new about Amy, and this is what this is about - creativity and positivity."
