(Spoilers) Lots of liberties taken in this film.
This movie took some BIG liberties with the numbers and stories. The real story is just as compelling and interesting, there was really no need to play with the facts the way they did.
Nobody committed suicide on board, two people did attempt suicide.
29 passengers (one non-Jew) got off in Cuba, not just the 2 shown in the film.
Scholars say of the 906 passengers who disembarked in Europe, 700 lived to see the end of the war. Many surviving against the odds in concentration camps and forced labor camps.
The remaining 206 sadly didn't live to see the end of the war. In a sad irony for some of them, they were put into internment camps by their host countries because they were Germans and considered "enemy aliens", no distinction was made because they were Jews or refugees. Those that couldn't get emigration permission were taken by the Nazi's when they invaded.
The ship was not lost during the war, it was damaged by bombing but was repaired and in service until it was scrapped in 1952.
