If you know your Titanic history well, the thumbnail for this article should look very strange to you. This is because "Titanic" director James Cameron had to deal with an interesting issue during filming, and this neat behind the scenes video takes a look at how he solved it.
"Titanic" was a massive undertaking, with a budget of $200 million (about $320 million in 2019), but of course, as we all know, it was rewarded, becoming the first film to gross over $1 billion worldwide and holding the record for total earnings for 12 years until it was eclipsed by "Avatar" (surprisingly, many predicted the film would be a huge financial disaster before its release). I stumbled across this video recently and found it quite interesting.
Even with its massive budget, the production still had to try to save money where possible. It turns out that Cameron made the decision to build the replica ship seen in the movie on the starboard side only. This choice was made because at the filming location, the prevailing wind moved from north to south; thus, this would blow the funnel smoke aft, making it look as if the ship was moving forward through the water. The problem was that the actual ship was docked on the port side at Southampton; thus, it would look like it was being loaded and boarded on the wrong side in the film. To get around this problem, everything in the Southampton scene was flipped horizontally: letters were reversed, costumes buttoned backward, and actors reversed their horizontal directions. Then, in post-production, the film was flipped.

I thought it was a pretty neat solution to the problem and impressive dedication to avoiding a historical mistake. Check out the top video for the behind the scenes commentary.
