I love this movie and I have always wondered since I saw that 2nd movie "Beyond The Poseidon Adventure" where that guy knew what was on board and was there straight away to get it.... Makes me wonder if they somehow created that title wave to cause the Poseidon to sink so they could grab the cargo....... They didnt ever hint to any of this but its just something I have wondered... What do you think guys?? It wouldnt be hard to cause a title wave in the path of that ship........ (A bomb going off far below for example) Its interesting to think about........
