There are rumors that Scarlett Johansson and Ryan Reynolds are having marital problems.  They reportedly got into a huge fight right before they were to appear together at Comic-Con, and he ended up not going.  I assumed he just staged a fight to get out of going to a nerd convention, but reports are surfacing that they are still in a rough patch and possibly separating.  Ryan's good friend Sandra Bullock is even stepping in to help the couple work it out.  What's she going to do to save their marriage?  A pratfall?
