Former “My Sister Sam� cast members Pam Dawber, David Naughton, Jennie O’Hara and Joel Brooks are scheduled to tape on Friday a handgun-control public service announcement dramatizing the loss of slain co-star Rebecca Schaeffer. According to Dawber, NBC, CBS and ABC have expressed interest in airing the spot, which will open with a publicity shot of the five original cast members. “Then it fades into the four of us on an empty sound stage, leaving a space where Rebecca should be,� said Dawber, who added, “This is real life. It’s not about show business. . . . The general public does not understand that we are just people who got lucky and happen to be on television. This was our friend.� Schaeffer, 21, was shot at her Los Angeles apartment July 8. Robert Bardo of Tucson, Ariz., is charged in the case.
