Galaxy Quest -- The alumni cast of a cult space TV show have to play their roles as the real thing when an alien race needs their help.

Hercules -- Hercules must go from zero to hero to save the universe from Hades.

Revolution OS tells the inside story of the hackers who rebelled against Microsoft’s proprietary software model and created Linux and the Open Source movement. Believing that computer software should be free - economically and intellectually - Richard Stallman and other high-profile technology experts started the Open Source movement. An admirer of Stallman named Linus Torvalds created a new operating system and called it Linux. Linux was freely distributed software that many programmers consider far superior to Windows. Revolution OS paints a compelling picture for tech heads and laymen alike.

For the past two decades, a group of computer hackers, neocommunists and entrepreneurs has been gradually undermining Microsoft's monopoly and fundamentally changing the way software is developed and owned -- a revolution that resulted in the Linux operating system and the Open Source movement. This fascinating documentary explores the OS movement's origins and depicts the grassroots nature of Linux and OS as they march into the mainstream.

The alumni cast of a cult space TV show have to play their roles as the real thing when an alien race needs their help.

A team of intrepid adventurers travels through the outer reaches of the galaxy, each week finding excitement and adventure on Galaxy Quest! Or at least that's the way it was in the mid-1970s, when brave if reckless Captain Peter Quincy Taggart, lovely Lieutenant Tawny Madison, and inscrutable alien Dr. Lazarus were the leaders of an interstellar law enforcement team on the TV series of that name. Twenty years later, the show is still in reruns, and Jason Nesmith (Tim Allen), Gwen DeMarco (Sigourney Weaver), and Alexander Dane (Alan Rickman) prop up their sagging careers by making appearances at sci-fi conventions, where they grudgingly shake hands and give autographs for the show's socially inept following. However, it turns out that nerdy sci-fi fans aren't the only ones watching: somewhere in another solar system, a group of alien rebels living under a regime of violence and repression have picked up broadcasts of Galaxy Quest, and they aren't aware that it's fiction. They travel to Earth and encounter the Galaxy Quest cast, who figure that they're just another bunch of guys who like to dress funny. However, they soon realize that they're being hired not for another autograph-signing session but for a real-life outer space rescue mission.

For four years, the courageous crew of the NSEA protector - Commander Peter Quincy Taggart (Tim Allen), Lt. Tawny Madison (Sigourney Weaver) and Dr.Lazarus (Alan Rickman) - set off on a thrilling and often dangerous mission in space...and then their series was canceled! Now, twenty years later, aliens under attack have mistaken the Galaxy Quest television transmissions for "historical documents" and beam up the crew of has-been actors to save the universe. With no script, no director and no clue, the actors must turn in the performances of their lives.

An outrageous odyssey of fun, fantasy, and adventure unfolds in the hilarious hit film HERCULES, Disney's 35th animated triumph "brimming with comic surprise!" (Entertainment Weekly) Taken from the gods as a newborn, adopted on earth, Hercules becomes an awkward teenage pillar of strength. Trying to fit in, he discovers his dad is Zeus and home is Mount Olympus -- if he can move from "zero" to true hero! Hercules teams with babyhood pal Pegasus, the flying stallion, and Phil -- a feisty personal trainer -- for the mission. But it's no easy task as he must match wits with Grecian beauty Meg and a comical hothead named Hades. With the help of Pain and Panic, Hades plans to rule the Universe with only Hercules standing in his way! With a bold animation style, colossal voice cast, and spectacular music, HERCULES is unmatched in strength -- delivering something for everyone with "pinwheeling, knockabout fun!"

Galaxy Quest was directed by Dean Parisot, who had a background in TV directing before his theatrical debut with the dark comedy Home Fries.
