winning  film _Titanic (1997)_ (qv). Although the Morse Code for SOS doesnt  appear in that movie, there are sufficient ways of excusing this  mistake (shes under stress, shes referring to another version of  the story, loads of people are absolutely convinced that they heard  SOS in Titanic (1997) even though they couldnt have, she just  doesnt remember where she heard it but supposes it must have been  there, etc) that its allowable as character error. She could also  be referring to the real Titanic, where many claim (incorrectly)  that the SOS sign was used for the first time.
