• This film is very rarely shown. As one of the biggest fans of the disaster movie genre, I can honestly say that the film is a disappointment. The Japanese version of this film was excellent from what I understand, but the American version that I saw was terrible. Lorne Green was dubbed in for American audiences in 1975 and the movie was retitled Tidal Wave. I believe 1973 is listed on IMD's records. I think you may be incorrect. I have always seen the movie date as 1975 everywhere else. The special effects are worth seeing as some of the acting, but again very disappointing as far as the tidal wave sequences. It is worth watching once if the networks ever air it again. This picture is very rare and almost forgotten.
