Sam Taylor-Johnson has admitted that she used to have "creative fights" with the author E.L. James on the set of 'Fifty shades of Grey.'
The 47-year-old said that there's no doubt it was difficult working with the British author and they use to fight on the sets but they were creative fights and so they always resolved them, E! Online reported.
The pair used to have "proper on-set barneys" over how the story should be represented on the big screen, she further added.
