Zac Efron’s “The Lucky One,” a heart felt romance adapted from author Nicholas Sparks’ novel, looks likely to claim the Number 1 spot at the box office this upcoming weekend. This could knock “The Hunger Games” from the top spot after a reign of nearly four weeks.

“The Hunger Games” has grossed more than $337 million in domestic theaters to date. It is thus far 2012′s top release, far ahead of “Dr. Seuss’ The Lorax,” with $204.5 million so far.However, there are other large blockbusters coming later in the year like “The Hobbit” which could surpass The Hunger Games for 2012.

If “The Lucky One” isn’t lucky enough to dethrone “The Hunger Games,” the honor may go to “Think Like a Man.” If the audience tracking surveys are accurate, each film could gross $20 million or more in its debut, which should be more than enough for the top spot.

“The Lucky One,” in which Zac Efron plays a soldier who appears to be protected by the photograph of a woman he doesn’t know, is appealing to younger women, the tracking surveys suggest. Men will either not attend or only go at gunpoint.

“Think Like a Man,” adapted from Harvey’s bestselling book, “Act Like a Lady, Think Like a Man,” is a relationship comedy starring Chris Brown, Kevin Hart and Regina Hall. Its core audience is older African American women, the surveys indicate, but it has broad support from younger black women and a good percentage of men.
