This is kind of bizarre. For a movie like this to make the most money, the time to strike would be just before the Olympics, or at least just after it. But if they're only just now talking about making it, then it will be at least six months, probably longer than a year, before it's released. They would have to change the storyline to something other than Salt Lake City / Torino.
And please remember that people talk about making movies all the time. They don't always get made.
