Angelina Jolie in 'Salt'Two of today's most popular movie stars, Leonardo DiCaprio and Angelina Jolie, go head-to-head at the box office this weekend, when Jolie's new spy thriller 'Salt' takes on last week's champ, DiCaprio's sci-fi mind-twister 'Inception.' DiCaprio has the edge, but Jolie is going to give him a run for his money.

There's also a new kids' movie opening wide, 'Ramona and Beezus,' but in an already crowded family market, it'll be lucky to finish in fourth place.

After last weekend's easy victory, 'Inception' has continued to perform well at the box office throughout the week. As the kind of puzzler viewers will want to see a second time in order to unravel its mysteries, it's expected to lose only a third or so of its business this weekend. Predictions range from $35 to $41 million, which should be enough for a second straight win.
