The writer of BBC series Peaky Blinders, Steven Knight, said he was "shocked" after the programme won the Bafta TV Award for Best Drama Series.
The crime drama set in 1920s Birmingham fended off competition from Netflix's The Crown and fellow BBC series Line Of Duty.
Speaking after receiving the prize from Doctor Who stars Jodie Whittaker and Bradley Walsh, Knight said he hoped the show would return for a further three series and even a film.
Knight said: "Our ambition is to make a story of a family between the two World Wars. I've always wanted to end with the first air raid siren in Birmingham in 1939.
"We're getting approached to do all kinds of things - the ballet, the musical and the movie would be great.
"I wouldn't want to do it at the very end but maybe in between two of the series."
Sue Perkins has said she will be putting in "half the effort" as she joked about the gender pay gap at the Bafta TV Awards.
Opening the ceremony at the Royal Festival Hall, she said it was the "original hostile environment".
She added: "I don't want to ignore the elephant in the room but it would be crass and inappropriate to discuss my fee, so let's just say I'm going to be putting in half the effort."
She also referred to the large Bafta masks that flanked her on the stage, saying: "I've still got two big fellas there, to make sure my driving is alright."

The Girls, the drama about the Rochdale child sex abuse scandal, has won the Bafta for best mini-series.
Writer Nicole Taylor dedicated the prize to health worker Sara Rowbotham and former detective Maggie Oliver, who helped blow the whistle on the issue.
Taylor, wearing a Time's Up pin, said: "To Sara Rowbotham and Maggie Oliver and the real three girls and their families, if people came to this programme it's because of you, you stood up in court, you went to the police."
She added: "To all the Maggies and Saras who lost your careers and nearly lost your minds trying to get your voices heard, thank you, this is for you."
