Accused murder Nick Reiner appeared anxious and rocked in his chair during his latest hearing as multiple supporters showed up in court.

Reiner — the 33-year-old son of slain actor-director Rob Reiner and his wife, Michele Reiner — seemed on edge in Los Angeles Superior Court on Wednesday.

Page Six observed Nick more antsy and alert than usual, as he looked directly at the judge and his legal team when responding to them.

He was wearing handcuffs on both wrists, but they were not connected to each other or attached to the chair that he rocked back and forth during the proceeding.

Nick also debuted a new look, opting to cut his hair and leave prominent sideburns while shaving the remainder of his face.

At least two fans were seated in the courtroom’s gallery, and they did not appear to be immediate family members.

Wednesday’s hearing was a continuation from Oct. 7, with Judge Sam Ohta once again extending the hearing to Jan. 13.

Ohta said Wednesday that Nick was “indicted unbeknownst to his counsel” and feels it’s appropriate to give the defense team more time, arguing that public access to the grand jury transcripts and exhibits that led to Nick’s July indictment is not more important than his rights.
