The “hero”, Anne Shirley, wishes to leave the ordinary world in which she resides– the unimaginative surroundings of both the orphanage and the home she worked in.
Anne seeks a way to address her outer problem (dull, hopeless environment) while also seeking an answer to her inner problem (identity questions, no family). Anne’s inner struggle is evident in the scene where she first meets the orphanage proprietor and indicates that her name is Cordelia. With the absence of her parents, Anne is in the process of creating a new identity for herself.
The call in the film takes shape in Matthew and Marilla’s decision to take in a male orphan, eventually prompting Anne’s arrival to Green Gables. The call acts as a way for Anne to approach her inner and outer problems (she is able to leave her ordinary world and also, find a family in Avonlea).
Marilla Cuthbert undoubtedly acts as Anne’s threshold guardian… outlining a “set of prescribed rules” for her quest/life at Green Gables. Similarly, Miss Stacy represents a shadow mentor who offers support, and exists as a source of inspiration to Anne. Several other female characters also support Anne’s later focalized quest to teach and write.
