 In 1973, Aaron Spelling developed two pilots with a similar theme:  this one and _Letters from Three Lovers (1973) (TV)_ (qv). In both  pilots, letters were delayed in delivery by one year per accident or  mischance; the delay would have a profound effect on the sender or  the recipient. Henry Jones played the postman delivering the long  lost letters in both pilots. Neither pilot was picked up for a  continuing series.
