With $31,000,000, the latest Spielberg’s movie, “Indiana Jones And The Kingdom of Crystal Skull” was the undisputable champion in this Friday’s box office.

The movie opened in the US on Thursday in 4,260 theaters and in the first two days, the new adventures of Indiana Jones and its partners earned $56,041,000.

“Indiana Jones and Kingdom of the Crystal Skull” bears very close resemblance to what made its “forebears” so popular and successful. It is still set in the past, in a Nevada of 1957, it still appears to have that ineffable old fashioned style that is so simple and in the same time, so unseen before, which becomes exquisite.

The intrigue of the movie is the eponymous crystal skull, an artifact believed to have been left by aliens in some of their first incursions on the Earth.

“The Chronicles Of Narnia: Prince Caspian” ranked second in this Friday box office, with $6,625,000. The movie, which opened last weekend, earned so far $74,670,000.

Produced by Marvel Entertainment and distributed by Paramount Pictures, “Iron Man” earned on Friday the third spot with $5,325,000.

Enjoying many favorable reviews, the movie boosted the career of Robert Downey Jr., who plays the role of Tony Stark, a billionaire weapons manufacturer who turns himself into a superhero, after being kidnapped by terrorists in Afghanistan. The movie earned $237,492,000 in just 22 days.

“What Happens in Vegas,” starring Cameron Diaz, Ashton Kutcher, Rob Corddry, Lake Bell and Dennis Farina, ranked fourth with $2,875,000.

Directed by Paul Weiland, and co-written by debutant Adam Sztykiel and Deborah Kaplan and Harry Elfont, “Made of Honor”, a romantic comedy gained the fifth place on Friday with $1,025,000.

“Speed Racer”, the new cinematographical effort of the Wachowski brothers, earned also $1,025,000 and the sixth spot. Based on the 1960s’ Japanese animation series “Mach GoGoGo,” which was initially inspired by a comic book of the genre and starring Emile Hirsch, John Goodman, Christina Ricci and Susan Sarandon, the movie is considered a disappointment.

The Top 10 was rounded by “Baby Mama” ($980,000), “Forgetting Sarah Marshall” ($495,000), “Harold And Kumar Escape From Guantanamo Bay” ($290,000) and “The Visitor” ($175,000).
