White feather, who is supposed to be the ghost of an American Indian, repeatedly says "How", regardless of what he is asked or what the situation is. In reality, no American Indian said "How". "Indian Speak" was created by Hollywood and unfortunately and unfairly stereotyped Indians for a long time to come.
The part of White Feather was quite a departure from the types of characters that Tenniel Evans usually played and who he was in his real life. He went on to become an Ordained Minister for the Church of England.
Valerie Lush, who played the psychic/medium Emily Tiffin, became an Eucharistic Minister for the Church of Our Lady in St John's Wood. Besides taking communion, she also brought food to the elderly and her humanitarian works were recognized by many organizations, including the Knights of Malta.
