Irish director John Carney has revealed that he regrets questioning Keira Knightley's skill as a "film actor."
The 'Fist 2 Fist' director recently took to his social media account to pen an apology to the 31-year-old actress and said he is ashamed that he could say such things, adding "in trying to pick holes in my own work, I ended up blaming someone else," reports E!online.
Branding his comments to be "arrogant" and "dispectful," Carney continued that "Keira was nothing but professional and dedicated during the film."
The post follows some "petty, mean and hurtful" comments Carney made about the acting skills of the 'Pride & Prejudice' star during an interview.
While Knightley has remained silent on the issue, Carney has received a lot of backlash for criticizing the actress.
Knightley and Carney had worked together in 'Begin Again'.
