Like many of the movies due out this summer, "Sex and the City" comes with a built-in audience that could translate into box-office bucks.
Based on the popular HBO series, which has also sold well on DVD, the movie picks up the story of Carrie Bradshaw and her BFFs four years after the show ended.
Despite a loyal following, Bock thinks "Sex and the City" will have difficulty competing with the more family-friendly movies out in May, which appeal to a broader audience.
Bock thinks "Sex and the City" is comparable to Tina Fey's "Baby Mama," which grossed $17.4 million in its opening weekend last month. Though some will call that type of debut a disappointment, Bock points out that a release in the range of $20 million is still "pretty good."
