Nick Reiner, the son of celebrated Hollywood director Rob Reiner, has appeared in court for the first time charged with murdering his parents.

The 32-year-old waived his right to enter a plea to two charges of first-degree murder at the hearing, as all sides agreed to delay his arraignment until 7 January when he will once again have the opportunity to enter a plea.

His lawyer, Alan Jackson, told reporters outside court that there were "complex and serious issues" in the case that needed to be worked through in the coming weeks.

Rob Reiner and Michele Singer Reiner were found stabbed to death in their Brentwood home on Sunday. Nick Reiner was charged with their murder on Tuesday.

As he appeared in court in downtown Los Angeles, Mr Reiner only said "yes, your honour" when asked by Judge Theresa McGonigle if he understood that he has the right to a speedy trial.
