Who plays Sandstorm in the warrior movie?

There isn't a Warrior movie yet and I don't think that there will be one because Warriors are fairly violent, and Erin Hunter doesn't go into detail so you interpretor what it looks like a lot when the cats are fighting. When you do a movie, you HAVE to see it so the movie would be either rated R or nothing like warriors. Sometimes, you don't mess with good things in life. So nobody is going to play Sandstorm.
