The redundantly-titled Further Adventures of the Wilderness Family, Part 2, is the 1977 follow-up to the successful 1974 independently distributed film (aka a "four-waller") Adventures of the Wilderness Family. The titular family, appropriately named Robinson, is once more headed by Robert Logan. The film contains the usual quota of brushes with danger and shots of cute woodland creatures, with the added complication of a bout of pneumonia suffered by Mrs. Robinson (Susan D. Shaw). Barry Williams, of Brady Bunch fame, sings the tunes heard on the soundtrack. Marketed on a theater-to-theater basis in the same manner as its predecessor, Further Adventures of the Wilderness Family scored a hit--resulting in yet another sequel, Mountain Family Robinson.
