After former Heroes co-star Greg Grunberg, who has an epileptic son, tweeted his outrage over a joke in the recent Tower Heist trailer referring to Ben Stiller as "little seizure boy," director Brett Ratner issued an apology and has reportedly asked Universal to alter the film's marketing. Grunberg tweeted his thanks and lifted "my personal boycott of ur hilarious film." No truth to the rumor Grunberg attempted to leverage his grudge in pursuit of Oscar-hosting duties, though presenting is probably not out of the question. [THR]
