InceptionAdd this to 'Inception's' list of puzzling, only-in-dreams feats: it's grossed $100 million in just seven days.

Having opened July 16 with an impressive $62.8 million weekend debut, Christopher Nolan's brain-bending sci-fi thriller continued to perform strongly throughout the week. As of Friday morning, July 23, according to estimates from distributor Warner Bros., the film has barely squeaked into the $100-million-in-one-week club with a total gross of $100,155,000.

Big deal, you say? Well, it doesn't happen as often as you might think. In fact, it's only the fifth movie this year to do so, after 'The Twilight Saga: Eclipse,' 'Toy Story 3,' 'Iron Man 2,' and 'Alice In Wonderland.' Plus, as Deadline Hollywood notes, it's the only film on that list that's based on an original idea and is not a sequel or reboot; nor is it in 3-D.

After last week's box office victory, 'Inception' is widely predicted to win again this weeknd, with the Leonardo DiCaprio hit adding a projected $35 to $41 million to its nine-figure earnings and fending off a strong challenge from Angelina Jolie in the new spy thriller 'Salt.'

In its seven days of release, 'Inception' has already become the 15th biggest hit of 2010 and the tenth biggest hit of the summer. After this weekend, it should rank at around No. 10 for the year, overtaking DiCaprio's earlier mind-twister 'Shutter Island' (the current No. 11 for the year), which earned $128 million during its four months in theaters.
