The cyber attack on Sony Pictures Entertainment exposed emails of numerous people, including one belonging to the company’s Co-Chairman Amy Pascal.

The emails were sent to film producer Scott Rudin and concerned President Barack Obama. One was reported as saying: "Should I ask him if he liked Django?", "The Butler" or "Think Like a Man," referring to films with African-American themes, reported BuzzFeed.

Pascal apologised for the statement made in the email saying: "The content of my emails to Scott were insensitive and inappropriate but are not an accurate reflection of who I am."

"Although this was a private communication that was stolen, I accept full responsibility for what I wrote and apologise to everyone who was offended."

Civil rights activist Al Sharpton was not happy with the apology claiming that it was "not enough", reported Reuters.

According to the Deadline Hollywood website Pascal contacted Sharpton.

Pascal added: "I realize I’m just going to have to move forward," she added, noting that she had work to do for this month’s releases of the films "Annie" and "The Interview. I have a company to run."

The receiver of the e-mail Scott Rudin also apologised about the incident.
