It's always fascinating to see how people who were once huge figures in pop culture can end up almost completely forgotten, leaving their work as emblems of the fleeting nature of fame. I came to Way Back Home as a Bette Davis fan, and she's certainly the one member of the film's creative team whose reputation has endured over the decades following its release, but Way Back Home is not a Bette Davis movie: It's a star vehicle for Phillips Lord, a massively popular radio personality bringing his well-known character Seth Parker to the screen for the first time. These days, it's unlikely that anyone but a hardcore old-time radio fan has heard of Lord or Seth Parker, but at the time the movie came out, both were huge stars.
That background info helps if you want to understand why this movie focuses on a 29-year-old guy in old-age makeup, delivering folksy wisdom to the backward residents of his small Maine community. According to Wikipedia, Seth Parker is meant to be a preacher, but he never sets foot in a church during this movie, and he spends most of his time just sitting around his farm and meddling in people's business. The movie's sense of humor is relentlessly corny, and Seth is an irritating busybody, although his lessons are sometimes remarkably progressive for 1931. Seth and his wife have adopted a young boy to save him from his drunken lout of a biological father, and their efforts to keep the violent man away from his son are the closest thing the movie has to a plot.
Elsewhere, Davis plays Mary Lucy Duffy, a young woman whose father forbids her from marrying the boy she loves, because he was born to an unwed mother. Even more than raising an orphan, Seth's handling of the Mary Lucy situation is pretty forward-thinking, as he defends the poor single mother from the scorn of the town, and does everything he can to make sure that Mary Lucy gets to marry her true love, despite what her father decrees. Davis' performance is earnest and sunny, and like every other actor in the movie, she plays second fiddle to Lord whenever he's onscreen.
The message may be slightly ahead of its time, but the delivery is as old-fashioned as it gets, with plenty of scenes that could have been lifted directly from radio, including long interludes of Seth singing hymns with his neighbors and an opening comedy bit that highlights the confounding logic of backwoods business dealings. Combined with the haphazard plotting, it makes the movie a serious chore to watch. I can imagine big Seth Parker fans in 1931 getting a kick out of seeing their favorite character on the big screen, and probably recognizing some of his signature radio bits. Divorced from its original context, however, Way Back Home is just a bunch of lame, hokey jokes strung together into a tedious narrative. (And while he continued to have a successful radio career, Lord never starred in another movie.)
