Mark Neveldine and Brian Taylor's latest piece of madcap action has a new name (from Game to Citizen Game to Gamer), a new poster, and a new trailer. Luckily though, it's still exactly the kind of film you've come to expect from the directing duo. The trailer looks like a pretty tasty mash-up of The Running Man, Death Race, Escape from New York, and Gladiator with a dash of Blade Runner for color. If you've been annoyed at Gerard Butler going all chirpy and chick-flicky lately, this trailer will be a nice dose of neo-Leonidas. He really snarles and smashes through every frame of this -- and he even does so shirtless just to keep the crowd that does like his chick-flicky side happy.

Of course, Butler may be the top name, but he's not the only draw. Michael C. Hall is splendidly slimy here, and you'll get glimpses of Logan Lerman, Chris "Ludacris" Bridges, John Leguizamo, Amber Valetta, and a blink-and-you-miss it shot of Kyra Sedgwick. Milo Ventimiglia and Alison Lohman are supposed to be somewhere in here, but it all happens too fast to see them.

It's silly for me to describe it further, so just check out the trailer below -- and if you have an XBox360, you can watch it there, but the rest of us have to get by with YouTube. Gamer hits theaters on September 4.
