The group are due to perform at the Glastonbury Festival this year
The story of a group of sailors from a Cornish fishing village who released an album of sea shanties could be immortalised on the silver screen.
The Fisherman's Friends - who are or were fishermen, coastguards or lifeboat men - were signed up for a record deal after they were seen singing in a pub.
Now Ealing Studios is working on developing a film charting the rise of the group from Port Isaac.
Jon Cleave from the group said their new career was "full of surprises".
The Fisherman's Friends, who have been performing shanties and folk tunes at the village quayside for years, landed their record deal with Universal after a producer visited and saw them.
Jokers And Rogues
Ealing Studios, which was behind films such as The Lavender Hill Mob and has recently been revived for films such as St Trinian's, said it wanted to capture the group's rise to fame on screen.
Head of studios Barnaby Thompson said: "The moment I heard the story of the band and listened to the songs, I knew this could be a great film."
A script is to be written by Nick Moorcroft and Piers Ashworth, responsible for both of the successful St Trinian's movies.
Mr Moorcroft said: "Their story has all the ingredients you look for as a writer.
"It is a heart-warming comedy about friendship, loyalty and community."
Film-makers aiming for a release next year and are using the working title "No Hopers, Jokers And Rogues", the name of a single to be released.
Mr Cleave added: "I don't think that any of us ever considered the possibility of a movie.
"It'll be lovely if Port Isaac was in a movie again.
"It was in Saving Grace, and it's been in lots of other films, so maybe a film that really portrays Cornish people. It would be fantastic."
The Fisherman's Friends are due to perform at Glastonbury Festival in the summer.
