The S.S. Poseidon is just leaving the harbor and already it’s starting to take on water. It might make $20 million this weekend, but it’ll be off a good 50% next weekend and with DaVinci Code and X-Men 3 ruling the roost over the next two weeks, Poseidon can do nothing except sink beneath the waves. If you calculate the distribution costs as roughly $50 million (which is what my estimate is) it doesn’t even seem probable that the domestic haul will match this amount. It’s an Alan Horn disaster movie.
