Sphere (1998) - This is quintessentially the movie for Thalassophobics like us. It has everything we find terrifying such as deep sea, monsters, pressure, cold, unknown and a dread that anything can end your life without your comprehension any minute.

For those who has not seen it I highly recommend it. It is based on a novel which is equally fantastic read.http://ift.tt/SBe1gC
