His friend and Star Trek costar William Shatner went on Twitter to express his sadness about not being able to attend the funeral service.
Shatner agreed to be at the Red Cross Ball tonight in Florida on Saturday night and can't make it back in time.
After sharing his feelings, he asks to remember his friend on Sunday and reminds everyone how much he loved Nimoy.
Nimoy passed away at his Bel-Air home. According to the actor's wife, Susan Bay Nimoy, her husband's passing was due to the end stages of chronic obstructive pulmonary disease (CPOD).
Nimoy sent out his final tweet about life on Feb. 23.
