"TERRIBLY OFFENSIVE TRAILER for #TowerHeist – Making fun @ people w/ seizures is NOT FUNNY & WRONG! "Seizure Boy!" REALLY? #Boycott RT," Grunberg tweeted on Thursday.
Ratner apologized to the Heroes actor, who then posted the director's mea culpa on his epileptic foundation's website, TalkAboutIt.org.
"I am so sorry you are offended ... I sincerely feel bad," Ratner said. Talk About It also reports that Ratner has asked Universal Studios to change the movie's marketing campaign by removing the offensive jokes from TV spots.
Grunberg's obviously not the type to hold a grudge. He responded with, "THANKS @BrettRatner for ur SINCERE APOLOGY to the Epilepsy Community! I'm lifting my personal boycott of ur hilarious film #TowerHeist RT"
