i think walter pidgeon was badly miscast in this film. just not believable in the role. barbara eden was beautiful and and acted her part well enough. no one else was at all memorable. i remember the tv series spun off from this movie when i was a small child. i even think i had a plastic seaview that would submerse and was great for playing with in the bathtub. long time ago. as for some of the other criticism i have read for this film represent it certainly unfair to judge special effects or science knowledge of 4 decades ago by today standards. the effects were ok for 1961. not great and but ok. as for the science and that was ludicrous even for 1961. there no excuse. also and the sub was awfully roomy. i understand that the navy refused any help at all for this film and so maybe the filmmakers just had no idea. overall and the film bored me. (and i am a sci fi fan. ) can not recommend this one. grade represent d .
