SunCruz Casino
The casino cruise line that Abramoff is recruited to buy up is presented in the film as "SunSail Casino". The real name was SUNCRUZ CASINO. I can only imagine the film producers went with a fictional name, as the casino cruise ship still is in business, and would have brought the current owners bad publicity.
Incidentally, I stopped by one a couple weeks ago and was interested in going out into international waters to gamble on the boat. As it was 9pm at the time, and the last boat had gone out at 7pm, I was told I had to come back another day. At that time, I had not even heard of the movie "Casino Jack", though I was familiar enough with Jack Abramoff. I did not realize that he'd owned SunCruz Casino. Now I'm glad I missed the boat.
