Now that "Gravity" is pulling audiences into theaters, moviegoers are getting their first look at the dramatic thriller about stranded spacewalkers.

The Warner Bros. Pictures' feature, which opened Friday (Oct. 4) nationwide, is a visual spectacle, in no small part due to director Alfonso Cuar贸n's desire to , a subject that has fascinated him since childhood.

"For me that whole idea of doing the setting in space and honor what is in there, not trying to invent, that was the thing," he told collectSPACE.com. "Why invent when you have the most amazing technology up there?" []

"Gravity" showcases the space shuttle, the Hubble Space Telescope, the International Space Station, and Russia's Soyuz spacecraft in stunning precision, including details that only those who share Cuar贸n's passion for spaceflight may recognize as being true to life. The film is "a piece of fiction," as the director puts it, and does take liberties with how the spacecraft operate in orbit, but Cuar贸n did not set out to make a documentary.

He did however, include some obvious and not so obvious  鈥� and even past space films. These may not be "easter eggs" in the traditional sense of hidden in-jokes or references, some of them may not have even been intentional, but here are five details that space enthusiasts might only notice in "Gravity."
