Doug Liman has committed to direct the Warner Bros. sci-fi project All You Need Is Kill, reports Variety. This solidifies a report from back in June that hinted Liman was circling the ambitious project; now it would seem as though the Mr. And Mrs. Smith director has finally signed on the dotted line. Variety doesn't offer many details other than that Liman has officially moved from the WB version of The Three Musketeers (which is competing with Paul WS Anderson's adaptation of the same material) to All You Need is Kill.  Dante Harper adapted Hiroshi Sakurazaka's novel, and there's no mention of a rewrite.  

The new teaser trailer for Gareth Edwards' low-budget wonder Monsters has just premiered at Apple.com, and it's definitely worth a look, so peep it below. Monsters, in case you're unfamiliar, was shot by newbie director Edwards for peanuts; the sci-fi movie utilized a two-man crew and a store-bought digital camera, while boasting realistic yet homemade special effects. Apparently, it cost somewhere in the neighborhood of under $10,000 to make. (And if you're thinking it's just another Paranormal Activity, check out the trailer to find out you're way off.) The flick, which has understandably drawn comparisons to District 9 (in terms of story), premiered to rave reviews at this year's South By Southwest Film Festival and has steadily gathered excited buzz ever since.

Alfonso Cuaron's Gravity might be spurring the hottest catfight known to man; Scarlett Johansson and Blake Lively are both vying for the female lead in the director's sci-fi thriller, reports the Heat Vision Blog, which undoubtedly creates all sorts of naughty visions in the heads of fanboys.

On 11/12/2010 audiences will get the chance to find themselves at the Skyline. The Strause Brothers latest journey into science fiction features something that is pretty darn terrifying, a mass alien abduction, but certainly not the kind we are used to seeing out of Hollywood.

Stephen Hawking’s warned us about the arrival of alien beings, the latest teaser trailer for the film explains. Meanwhile, massive blue lights come crashing down into homes and businesses as it leaves only rubble and smoke filling up the sky.

Check out the new trailer for the Strause Brothers' upcoming Sci-Fi, Thriller Skyline...

Synopsis: In the sci-fi thriller Skyline, strange lights descend on the city of Los Angeles, drawing people outside like moths to a flame where an extraterrestrial force threatens to swallow the entire human population off the face of the Earth. Skyline is directed and produced by the Brothers Strause (Alien vs. Predator: Requiem), whose company Hydraulx has provided visual effects for Avatar, Iron Man, The Curious Case of Benjamin Button and 300.

Riley Keough, perhaps better known as Lisa Marie Presley's daughter and the granddaughter of Elvis Presley, has been tapped to co-star alongside Tom Hardy and Charlize Theron in George Miller's Mad Max: Fury Road (aka Mad Max 4).

The actress is still "in talks" for the role; Keough would play one of the "Five Wives", a group of women that Mad Max (Hardy, Inception) is protecting. Teresa Palmer, Adelaide Clemens and Zoe Kravitz play three of the other wives. (Kravitz herself is the daughter of musician Lenny Kravitz.)

There's been plenty of discussion regarding a sequel to James Cameron's Avatar; it's really more of a "when" not "if" discussion, because of course when you've got the biggest movie of all time on your hands, it's a foregone conclusion that you're going to churn out a few more.

Inception star Cillian Murphy is getting ready to join Justin Timberlake and Amanda Seyfried in Andrew Niccol's (Gattaca) sci-fi thriller I'm.mortal, reports Heat Vision Blog. While Murphy is a benevolent figure in Christopher Nolan's Inception, he's played many a bad guy in his time, most notably in Nolan's Batman Begins and Wes Craven's Red Eye. Seems like he'll be doing so again in this futuristic suspense flick...

Maggie Grace must have liked getting Taken so much, she wants to do it all over again! Deadline.com is reporting that the former "Lost" star is set to appear in Lock Out, which would reunite her with Taken writer-producer Luc Besson. The concept of the film? Why, it's "Taken meets Escape from New York... in Space!"

Guy Pearce is also attached to star in the film. Pearce would play a man wrongly convicted of conspiracy to commit espionage against the U.S. He's offered his freedom if he can rescue the president's daughter from an outer space prison taken over by violent inmates. Grace, of course, is playing the daughter.

Tron: Legacy director Joseph Kosinski has shored up his follow-up film, Oblivion wih Disney, which obviously sees the helmer as an important cog in their live-action future. Kosinski had been shopping around the property, which will debut as a comic book from Radical Publishing this fall, to all the major studios after Comic-Con, but it was never really in doubt that the Mouse House would want to keep the promising director on their lot, considering all the good buzz Tron is currently building.
