Joanna Lumley is the driving force behind the 'Absolutely Fabulous' movie.
Jennifer Saunders is currently re-writing the script for the much-anticipated movie, but has revealed it was her co-star who been encouraging her to transform the iconic sit-com into a film.
Jennifer - who played Edina Monsoon in the BBC show - explained to the Radio Times: "I think I have everyone [from the original cast] back on board.
"It was Joanna's idea, so she will have to buckle down. She's the one who told me I had to write it, so it's all her fault!"
The 56-year-old star recently revealed the movie, titled 'Edina and Patsy' - after the show's central characters - is her focus for 2015.
She shared: "I've finished the first draft. I'm feeling euphoric.
"My proper New Year's resolution is to do the film, otherwise it'll be a pointless year of procrastination."
Jennifer also confirmed Julia Sawalha and June Whitfield will both be returning to their original roles for the movie.
However, the writer has also conceded the creative process has been creating stress.
She joked: "I am actually having treatment, hypnotherapy, for procrastination. It's true, What my hypnotist said was to get rid of the backpack of negativity."
