In keeping with tradition, the producers of 'Scream 4' have tapped a pair of stars to take on cameo roles in the next installment of the franchise. Anna Paquin and Kristen Bell will do the honors for director Wes Craven this time around, according to HeatVision. You will recall that Drew Barrymore kicked off the original 'Scream' in 1996, getting killed off quite gruesomely in the opening scene of the film. Jada Pinkett Smith and Omar Epps made cameos in 'Scream 2.' There's no word as to what will happen to Paquin and Bell.
