Dreyfuss claims dad, uncle owe $4 million

The Oscar-winning actor sued the pair in August over the loan, but amended his lawsuit this week to raise new allegations of financial wrongdoing. Dreyfuss' complaint states he loaned his father and uncle $870,000 in the early 1980s to help them with a 13-story office building they own in downtown Los Angeles.

In court documents, Gilbert Dreyfuss denied the loan was that old and stated that his nephew didn't have a large enough stake in the building to warrant repayment. He did not immediately return calls and e-mail messages seeking comment.

Dreyfuss is seeking to look at accounting records for the building, and repayment of the loan and interest.
