Making a movie takes time. Sometimes the co-stars will be spending most of the time together for months on end, and even if they are Hollywood superstars, they're still just humans and they have the same needs and desires as everyone else.
It shouldn't really come as a surprise that some of these celebs hooked up, or even took their relationship to the next level. It actually makes perfect sense. They're dating someone at their own level, and just as important: someone who knows what it's like to be famous and will be able to handle the pressure once the relationship gets leaked to the press. Sometimes these things are just a fling and will fizzle out once the filming is done, other times they end up as one of Hollywood's super couples.
