"Paranormal activities take a liking to [Ilyssa]," said Milano. "So crazy things sort of happen ... she can't figure out why, but we'll eventually, at the end, figure out why." It sounds like the leading lady is at the heart of the mystery for this new Ghostbusters outing. And apparently, there's lots of "flirty, flirty sexual tension" happening between Venkman and Selwyn, too. At least, that's what Milano says ... We can't imagine how much sexual tension there could possibly be starring opposite Bill Murray.
