The second to last actor goes into the room and closes the door for his audition. Judge said that the actor was in the room for quite some time longer than the other actors. Judge added that he could hear shrieks of laughter coming from the people inside the room.
The second the last actor was Robin Williams. He and Judge Reinhold were auditioning to play the space visitor Mork on Mork and Mindy.
The rest is TV history.
