I'm not sure when did this all take place, but there was a tiny bit of a zombie outbreak in GSC cinemas in the Klang Valley. Any chance you were there when it all happened?
Note that I didn't review the film for reasons I won't disclose here. But word has it that KL Zombi is praised for its visual style and effects, while others argue that it didn't fully live up to its potential (you can partially thank the LPF for that). Well, it's doing rather well. Last I heard it has already went past the RM2 million mark after four or five days. Go catch it and later talk about it.
Maybe Grand Brilliance will hear you out should they ever decide to make a sequel.
