 The above cast members appear in the opening credits in "cameo" display — sequential pictures of each actor with his/her name (and sometimes character name) superimposed at the bottom of the screen — for the first episode, followed by a listing of supporting players.Subsequent chapters simply listed the stars on one screen and the same supporting cast a second.This approach to cast display was used by Republic from its first serial through "Haunted Harbor" in 1944.
