Time to get home to kids: Russell Crowe

Russell Crowe says it's time to get home to Sydney to be with his children.

"Starting on another film set tomorrow. I need to go home & be with my children. Cannot believe how f***ed up my schedule has become this year," he tweeted on Tuesday.

Crowe, 48, is in the final stages of an very busy year professionally, during which he has filmed five movies overseas.

It's recently been revealed that Crowe and his wife Danielle Spencer have separated, and only this week he announced he was selling his stake in NRL club South Sydney.

He cited a desire to spend more time with his family as a primary reason for cutting his financial ties with South Sydney.

Crowe and Spencer have two sons, aged eight and six.

In an earlier tweet, Crowe said: "Started the year knowing I had 4 movies to do. 5 in a row if you count Man of Steel. Only 1 short stint left on Winter's Tale then home."
