I always found The Long Voyage Home a rather dull film. It is based on Eugene O’Neill play and is largely stage bound with a lot of the regular Ford ensemble hamming it up big time.
Duke has little to do in the movie other than play a young naïve Swede. Considering that this film is post Stagecoach it is a major disappointment to John Wayne fans as it does not develop the qualities of John Wayne in any way and has very little to recommend it.
The role actually reminds you of those played by a young Harry Carey Jr in later Ford movies.
I can only assume that Duke did this film in gratitude to Ford for Stagecoach. In my opinion it is a major yawn which you will watch once and then leave on the shelf!!
