Check out this trailer from Sylvester Stallone's fourth adventure as super-soldier and man of few words, "Rambo." Like last year's "Rocky Balboa" Sly's gone back to the basics of one of his most beloved characters. In this movie, John Rambo's living a quiet, peaceful life near the Thai-Myanmar border in Northern Thailand. Unfortunately, he soon gets involved in the bloody civil war going on down there while trying to save some missionaries -- and from the looks of this trailer, things gets really messy. Stallone's said in interviews that he wanted to make "Rambo" grittier and much more violent than the first three. He said the idea for this movie came to him after he called up the editors at "Solder of Fortune" magazine and they told him Burma had the worst cases of human abuse happening anywhere on the planet.

"Rambo" arrives in theaters January 25, 2008.
