Movie studios have been mining the videogame industry for creative ideas since the early 1990s. Given nearly 20 years to crack the formula, you'd think that Hollywood would have a better track record. Sadly, many game-to-film adaptations haven't lived up to expectations; Super Mario Bros., Street Fighter, and Wing Commander are some of the worst offenders.

The film biz still has plenty of chances to get it right, as there are now more than 50 videogame adaptations in various stages of development. Because we're all about bringin' you the info, we've compiled this helpful guide to all of the flicks based on games that Hollywood is toying with, from familiar names like Castlevania to more recently announced projects like Call of Duty . Here you'll find alphabetized entries for each movie, the project's status, and an update on each film - some with new and exclusive tidbits!UPDATE: Ada Wong becomes the latest Resident Evil mainstay to appear in Retribution. Status: In DevelopmentAmerican McGee's Alice was an instant hit when it debuted on the PC back in 2000. The gaming title has long since lost its luster, but the concept is still ripe for film adaptation. Recently, producer Scott Faye (Max Payne) updated the interwebs with a status on the project: Sarah Michelle Gellar is no longer attached to star and Texas Chainsaw helmer Marcus Nispel is, yep, no longer attached to direct. A new script is in development by original Alice scribes Jon and Erich Hoeberand, and word 'round the campfire is that a new studio will be announced in the future, as Universal is no longer attached to release the project.As in the game, the film will be a gothic-horror version of Alice in Wonderland that takes place after Alice has been committed to a mental institution. Status: UnknownAlice creator McGee has also plotted a twisted version of L. Frank Baum's fabled Land of Oz. The game itself was canceled after publishers balked at the pitch, worrying that it was not an established franchise. McGee then decided to build the franchise from the top down -- developing the characters and a movie pitch first. Jerry Bruckheimer and Walt Disney Pictures have obtained the rights -- a trilogy was once rumored -- but the project appears to be stalled in development. Screenwriters Kevin and Dan Hageman were once attached. Status: UnknownParamount Pictures optioned the movie rights to Midway Games' sci-fi themed first-person shooter, Area 51 , several years ago. Producer Christine Peters was handling the project, collaborating with the game developer to craft the film, billed as an action-packed thriller. Area 51 is set in the mysterious top-secret facility located in the Nevada desert.Specialist Ethan Cole (voiced by David Duchovny) has been sent to investigate a viral outbreak that has just shut down the research facility, automatically locking all personnel inside under quarantine. He soon realizes that the conspiracy theories and alien autopsies the world has speculated about are far worse than anyone could've imagined. The game also features the voices of Powers Boothe as Major Bridges and Marilyn Manson (appropriately enough) as Edgar, the gray alien. The creatures in the game were designed by Stan Winston Studios. As you can see it's a ripe property for feature film development, but now that the game has aged, we'll presume this one has been put out to pasture unless otherwise notified. Status: In DevelopmentEA have several of their videogame properties in development as films, and Army of Two is one of the more recent additions to the roster. The game features a pair of private military contractors who rely on teamwork and extreme violence to survive the gritty world of modern warfare. Scott Stuber is producing the film , with Scott Z. Burns (The Bourne Ultimatum) penning the script. We haven't heard much else since this news last October, though. It's possible the project has been put on the back burner, but with a new Army of Two game in the works we assume more news will trickle out eventually.Status: In pre-productionYour eyes aren't deceiving you. The early Atari classic Asteroids has been optioned for film and seems to be moving steadily along. The series has found its home at Universal with Lorenzo di Bonaventura (Transformers) producing. Writer Matthew Lopez is currently penning the script.Roland Emmerich was up for directing the film, but the director has moved on to another project, his top-secret sci-fi film Singularity.So what's the plot of Asteroids? The story centers on an Earth that's already been destroyed by some sort of 2012/ID4-y event, and the human survivors are living on colonies within an asteroid belt, along with aliens who they learn were responsible for Earth's destruction.At the rate things are developing we might learn sooner rather than later whether this gaming classic can thrive on screen. Status: In DevelopmentWith its heady undertones of Objectivism, BioShock may be the closest Hollywood ever gets to turning out a film version of Atlas Shrugged. But with genetically modified goons and lumbering monsters in diving suits livening things up, viewers won't have to worry about falling asleep during the characters' long sermons.Gore Verbinski (Pirates of the Caribbean trilogy) has been attached to the BioShock movie since shortly after the first game's release in 2007. Verbinski even went so far as to drop out of the upcoming fourth Pirates film to concentrate on BioShock. However, his commitment to Rango with Johnny Depp has forced Verbinski to fall back into a producer role. 28 Weeks Later director Juan Carlos Fresnadillo was set to replace Verbinski, until Fresnadillo left the production to direct a horror movie titled Intruders and starring Clive Owen.But it looks like Juan Carlos is back in the director's chair. We recently chatted with Verbinski about the project , and he revealed that Fresnadillo is still attached to direct. At the moment, it looks as if Verbinski, Fresnadillo, and Universal are trying to determine how to keep the underwater horror film under a reasonable budget that strikes a hard R-rating. Luckily, Verbinski also noted that the udnerwhelming box office performance of Prince of Persia won't impact BioShock's future.Rapture's cinematic future isn't without hope. Status: TrademarkedCall of Duty is one of the most recent names to be thrown into the Hollywood hat, but already the notion of a big-screen version of these games has fans salivating. Last month, Activision filed a trademark for a Call of Duty movie. Robert Bowling of Infinity Ward hinted on Twitter that talks have already begun with Hollywood studios.Kevin McKidd, the voice actor for Captain Soap MacTavish in Modern Warfare 2, recently spoke about the film . After remarking how Soap was modeled after Gerard Butler, McKidd discussed the possibility of reprising his role on screen, saying, "If the script is good, and Gerard isn't available [laughs], then absolutely!"Nothing else is known at this stage. It's believed that a Call of Duty film would more likely focus on the Modern Warfare games rather than those set during WWII, but we won't know for sure until further announcements are made. Status: In DevelopmentLike the vampire lord Dracula himself, the Castlevania movie keeps vanishing into the mist and rising from the dead. Paul W.S. Anderson (Resident Evil, Mortal Kombat) has been attached to the Castlevania movie for many years now. When Anderson spoke with us in 2008, he indicated the looming SAG strike had put the project on indefinite hold.But things are looking up for Castlevania again. At SDCC this summer, James Wan (Saw) revealed that he is now attached to direct the film and co-produce with Anderson. The project's producer and Paul W.S. Anderson recently revealed that they are waiting for a script to come in before moving on to next steps. Wan admitted that he was in the early stages of development, so we're not really expecting to hear much for a while. But assuming no more industry strikes arise in the near future, Castlevania may finally be headed to Hollywood. Status: In DevelopmentOddworld creators Lorne Lanning and Sherry McKenna are bringing their best-selling videogame property to the big screen in Citizen Siege, a CG-animated film that will be set in the Oddworld universe. The movie will be set in a frightening near future where democracy has all but disintegrated under the rule of global corporatism. Lanning is making his directorial debut with the project and McKenna is producing. The pair have hinted that there may also be a new game that will parallel the film's action. Status: In DevelopmentBased on the popular Capcom videogame, Clock Tower tells what happens when an Ivy League-bound high school girl gets a call from the birth mother she doesn't remember. Seeking out her childhood home, the girl and her sister confront a timeless horror in the form of an entity known as Scissor Man. The script is penned by Jake Wade Wall (When a Stranger Calls), and Jorge Olguin (Sangre Eterna) is set to direct. Clock Tower is being produced by Mayhem Project who confirm that the picture is very much in development, but could offer no further details.
