Guest stars include Anne Lockhart who was one of the original contenders to play Laurie Strode in Halloween (1978) until Jamie Lee Curtis won the role and George O'Hanlon, Jr. who did appear in the original Halloween's opening scene as the father of the infamous Michael Myers. If you go by the first sequel's revelation in Halloween II then he was Laurie Strode's father too. O'Hanlon, Jr. and Jamie Lee Curtis appeared in an episode of Hardy Boys/Nancy Drew together.
