Probably the most common gripe people had with The Hangover Part II was that it was way to similar too The Hangover. Director Todd Phillips promised he would redeem himself in the third and final entry of the trilogy by making The Hangover Part III the darkest film of the three by killing off one of its vital characters.

Looking at the teaser trailer for The Hangover Part III, there are a lot of characters from the previous films that come back to reprise their respective roles, but one character is notably absent from it. Find out who after the jump.

Ever since Sin City: A Dame To Kill For went into production, director Robert Rodriguez has continued to expand his mighty impressive ensemble cast on a weekly basis. Last week Eva Green signed on to play Ava Lord, the titular dame at the center of the action, and today we have word that the movie’s main villain has been cast. Stacy Keach, the veteran character actor with a career that spans more than five decades in film, theater, and television, has joined A Dame to Kill For as the crime boss Wallenquist, described by Sin City creator Frank Miller as “the one man who can’t be redeemed in Sin City. He is pure evil.”

Now this movie has become a must-see as far as this writer is concerned. Keach has long been one of my favorite actors and he has an acting resume that even the biggest male movie star in Hollywood wishes they had. He got his start in the late 1950s on the syndicated comedy series How to Marry a Millionaire, but it took nearly ten years for him to make the leap to feature film acting. Keach was one of the most in-demand actors of the 1970s with roles in movies like Brewster McCloud, The New Centurions, John Huston’s brilliant boxing drama Fat City, the cult classic action-comedy The Dion Brothers, and the Jim Thompson adaptation The Killer Inside Me. Fans of the Cheech and Chong movies will recognize him as the doping duo’s police nemesis Sgt. Stedanko in Up in Smoke and Nice Dreams.

Robert Rodriguez has been promising a sequel to Sin City, the 2005 over-the-top noir comic adaptation he co-directed with its creator Frank Miller, since the original became a smash hit in theaters and on home video. Up until a few months ago there had not been much movement on the project outside of unfulfilled promises and expectations, but production on the upcoming Sin City: A Dame to Kill For – a sequel that will be a combination of previously published comic stories and all-new material conceived by Miller – has been going on at Rodriguez’s Troublemaker Studios in Austin, Texas for a while now.

Every week seems to bring exciting news on the casting front with original stars Mickey Rourke, Jessica Alba, Rosario Dawson, and Jaime King reprising their roles alongside new cast members Josh Brolin (playing Dwight, Clive Owen‘s character from the original), Jamie Chung (stepping in for Devon Aoki as the deadly sword-wielding Miho), Dennis Haysbert (replacing the late Michael Clarke Duncan as brutal underworld enforcer Manute), Ray Liotta, Juno Temple, Christopher Meloni, and most interesting of all, Joseph Gordon-Levitt.

After having just been informed that Joseph Gordon-Levitt had been added to the cast of Robert Rodriguez and Frank Miller‘s Sin City sequel, Sin City: A Dame to Kill For, now comes word of two more actors joining the cast.

According to sources, both Josh Brolin and Christopher Meloni have now joined the cast of the sequel, which is based on Miller’s comic series.

In the 2005 movie Sin City, Michael Clarke Duncan played a bad dude named Manute, who had a run in with Dwight (Clive Owen), Gail (Rosario Dawson), and her girls.

The character will also be part of the upcoming long awaited sequel, Sin City: A Dame to Kill For, but, due to the sad and unexpected death of Clarke Duncan, a replacement was necessary.

It’s being reported that Dennis Haysbert, star of the hit TV series 24 and movies like Major League, has entered into negotiations to step into the role.
