This came as Marks & Spencer became the latest firm to pull its ads over the issue.
Other films to pull its advertisements include HSBC, Lloyds, Royal Bank of Scotland, BBC, Channel 4 and McDonald’s.
Matt Brittin, Google’s head of Europe, the Middle East and Africa, said today: “I want to apologise to anyone affected.”
He also said its “automatic filtering system” for placing adverts would be improved.

An M&S spokesman also said today: “In order to ensure brand safety we are pausing activity across Google platforms while the matter is worked through.”
The Cabinet Office has also put a restriction on YouTube advertising “pending reassurances from Google that Government messages can be delivered in a safe, appropriate way”.
Google’s UK managing director, Ronan Harris, has admitted it “can and must do more” to combat what it called “bad advertising”.
He said: “We will make changes in the coming weeks to give brands more control over where ads appear.”
