Now that Eclipse has finally opened, and Twi-hards everywhere are flocking to theaters (and taking husbands and boyfriends with them) this Fourth of July weekend, we're wondering if the third installment will follow the trend of its predecessors. Twilight and New Moon got fans into a frenzy that had them returning to theaters for multiple viewings. So far, the LA Times reports Eclipse's sales have trailed New Moon's but it's still expected to make $180 million by Monday. Of course, that's dependent on how many trips you're taking to the theater this weekend.
