Those Smokes Didn’t Exist Yet
Jack has a pretty bad smoking habit in Titanic. If anyone smokes out there, we recommend you put your cigarettes out right now and toss them in the garbage. Now that that’s out of the way, we can focus on Jack’s choice of smokes.
There were far more smokers back then than there are now, so it makes sense for Jack to light up every once in a while. The problem is the cigarettes—they’re mass-produced filter cigs that weren’t in production for another few decades, or the 1950s to be exact. Jack truly was ahead of his time in numerous ways.
