I'LL BE BACK, as the Governator whould say. Tomorrow. Angels & Demons was your No.1 movie this weekend, but its 48 million was far less than the DaVinci Code's 77.1 million, or Star Trek's opening last weekend. Trek made 43 million, a fairly impressive hold. This week it will become the most successful Trek since the 1980s. Trek is now almost certain to clear 200 million in the US, a big relief for Paramount. Wolverine is in third and plummeting. Rounding out the Top Five this week are the counter-programming, Ghosts of Girlfriends Past and Obsessed.
