20 Things You Somehow Missed In Titanic
3. The Film Depicts The True Story Of Baker Charles Joughin
One of the sly character subplots unfolding in the movie's background is that of Chief Baker Charles Joughin (Liam Tuohy), a real life Titanic survivor who spent roughly two hours treading water yet was rescued with only minor injuries - a fact he attributes to drinking alcohol throughout the sinking.
In the film, we briefly see Joughin earlier on taking a swig from a flask of booze, and he reappears during the climax, where he once again has a cheeky drink while riding the Titanic down into the sea with Jack and Rose.
To the lay-person it seems like nothing more than an invention of Cameron's, but in fact he was paying tribute to one of the ship's most shocking survival stories.
