The first trailer for Gavin Hood‘s large-scale adaptation of the classic Orson Scott Card sci-fi novel Ender’s Game is set to premiere early this week, but in the meantime, stars Harrison Ford (Colonel Hyrum Graff) and Asa Butterfield (Ender Wiggin) are here to tease some footage from the upcoming trailer.

You can watch the footage with the Ford/Butterfield intro here below.

The full trailer will debut on Tuesday, May 7 at 1:00 PM PT/4:00 PM ET during a Google Plus Hangout in which director Hood, star Butterfield, and producer Roberto Orci will be on hand to discuss the movie. You can tune into the Hangout at YouTube.com/EndersGameMovie and Google.com/+EndersGame and submit questions for the trio to answer during the discussion. I wouldn’t count on Card’s long-held stance on same sex marriage to be addressed though.

The long-gestating film adaptation of Orson Scott Card‘s classic sci-fi novel Ender’s Game is in full swing with a solid director in Gavin Hood (Tstosi) and a stellar cast. Producer Roberto Orci has been providing regular updates on the progress of the film through his Tumblr production blog.

Yesterday Orci posted a picture of the film’s young hero Ender Wiggins with a monitoring chip implanted on the back on his neck. Check out the image here below.

Orson Scott Card‘s classic 1985 sci-fi adventure novel Ender’s Game has been targeted for the celluloid treatment for several years, at one point with Wolfgang Petersen (Das Boot) in the director’s chair. Last year, Summit Entertainment finally got an Ender’s movie into production with Gavin Hood (Tsotsi) directing and writing the screenplay adaptation.

The project has attracted a cast of acting heavyweights and up-and-coming young stars with 15-year-old British actor Asa Butterfield (Hugo) in the title role of a brilliant child who joins a program designed to produce military officers out of bright children for a war Earth is waging with an alien known as the Formics, or “buggers.” Joining Butterfield are Abigail Breslin (Zombieland), Hailee Steinfeld (True Grit), Ben Kingsley (Sexy Beast), recent Oscar nominee Viola Davis (The Help), and Harrison Ford – no stranger to fighting in interstellar wars on screen.

Orson Scott Card crafted one of the greatest science fiction saga’s of all time with the Ender books starting with Ender’s Game. Marvel talent and Card have been bringing Ender’s story to comic books and now an all-original story, the prequel to Ender’s Game, is coming to comic book form first. The 7-issue miniseries called Formic Wars Burning Earth is written by Orson Scott Card and Aaron Johnston with art by Giancarlo Caracuzzo.

Marvel is partnering with ComicsPRO retailers to release the first installment of the miniseries a day early on February 14, 2011. These retailers will be celebrating this story by offering some great sales on the other Ender collections. If you’re in Chapel Hill, NC, you may want to head over to Chapel Hill Comics that day where Card and Johnston will be on hand to sign the comic.

The LA Times spoke to author Orson Scott Card, who’s currently promoting his direct sequel to Ender’s Game, Ender In Exile, and during the conversation, the movie adaptation that was supposedly in the works was brought up. Last we had heard was of Wolfgang Peterson‘s departure from directing duties (see Wolfgang Peterson Leaves Ender’s Game), but nothing since.

In what came as a great surprise, Mr. Card told them that the latest movie project had been scrapped because he “did not feel comfortable with the movie’s direction.” It was also explained that this and other attempted projects never worked because of Card’s refusal to allow his property to fall into Hollywood’s love for “tough-hero action films” and their usage of the green screen. He also clarified that he would still love to see an Ender’s Game movie, but he says the only way to make the movie work is when “…the human relationships are absolutely essential — an honest presentation of the story.”
