Phoebe Waller-Bridge was "shocked" when she re-read her original \'Fleabag\' script.
The 34-year-old star - whose live stage show was adapted into a hit BBC Three comedy - admitted she even left herself stunned when she revisited her script years after first taking the project to the Edinburgh Fringe Festival.
In an interview with \'The Graham Norton Show\' - which will be aired tonight (24.04.20) - she said: "I was in my mid 20s when I did it originally and everyone involved was full of attitude, and totally unapologetic about what we wanted to say and do with the work.
"When I re-mounted it in New York in my early 30s I remember in the first rehearsal opening the script - which is quite a lot edgier that the TV show - and genuinely being quite shocked and a bit embarrassed.
"I really didn\'t think I could say some of the lines. But once I got back into the character it was a lot easier."
Earlier this month, Phoebe revealed her theatre production - recorded at Wynham\'s Theatre and originally broadcast in cinemas in September last year - will be coming to Soho Theatre On Demand and Amazon Prime Video to raise money for UK charities helping during the coronavirus pandemic.
The project - which launched in partnership with National Theatre Live - has been unveiled for a good cause, and the writer joked it was the "only bit" of the series she hadn\'t "rinsed dry".
She added: "Last year\'s stage show recording is the only bit of \'Fleabag\' that I haven\'t completely rinsed dry out in the world! So why not do it for a good cause."
