The soul to be captured in this episode, a shipping magnate who swallowed his fortune rather than share it, is named after the SS Edmund Fitzgerald. The Edmund Fitzgerald was a Great Lakes freighter which sank on November 10, 1975 during a storm on Lake Superior and was commemorated in the 1976 hit song by Gordon Lightfoot, titled The Wreck of the Edmund Fitzgerald.
The soul of Edmund Fitzgerald is played by the same actor who goes on to play a reaper himself in Supernatural.
The type of car Morgan drives is a Maserati Spyder. That company's logo is a stylization of a Neptune's trident, also akin to the Devil's pitchfork.
