Originally broadcast in 1979, Marine Express is the second of two made-for-TV movies produced by Osamu Tezuka (the first being Bander Book). Marine Express uses familiar and less familiar Tezuka characters together in a new story in a similar fashion to 2001`s Metropolis. Set in the year 2002, the Marine Express is the latest in trans-pacific travel and in its final testing stages. But when the train`s construction chief is found dead, a mystery begins to unfold as the train departs on its maiden voyage.
