Don't watch this film if you are a stickler for details; most of the sets are inaccurate and there are anachronisms galore. There was no siren wailing during the sinking; the ice sliced open the starboard (right) side, not the port (left), there are countless other errors in this film too many to count. What makes it so watchable? Why, Barbara Stanwyck and Thelma Ritter of course!!! Stanwyck gets the histrionics as only she can deliver them while Ritter gets all the wisecracking one-liners - as only SHE can deliver them. Robert Wagner and Audrey Dalton make a beautiful couple, but they take a backseat to the two "tough broads" of the silver screen. Even Clifton Webb seems weak and prissy here. But then to me, he always does. The script has crackling dialogue and deservedly one an Oscar for Best Original Screenplay.
