Vietnam Vet John Rambo Returns for One Final Mission

Sylvester Stallone first starred as John Rambo back in 1982's "First Blood," a remarkably insightful portrait of a Vietnam War veteran struggling with PTSD while fighting to protect himself against idiot small-town law enforcement.

Rambo returned in 1985 as an '80s action superhero in "Rambo: First Blood Part II," returning to Vietnam to free POWs and kick some ass. It's probably best to forget about 1988's "Rambo III" and 2008's "Rambo."

It's more than three decades later, and Stallone returns to wrap up his black ops military career with "Rambo: Last Blood," coming to theaters on Sept. 20. Lionsgate has launched the first trailer. You can watch it below.

Stallone came up with the story and co-wrote the script. Adrian Grunberg, who helmed Mel Gibson's 2012 action comeback "Get the Gringo," is director on "Last Blood." The new movie co-stars Paz Vega, Sergio Peris-Mencheta, Adriana Barraza, Yvette Monreal, Genie Kim aka Yenah Han, Joaquin Cosio and Oscar Jaenada.

This time, Rambo's gotta clean up some bad hombres from a drug cartel. There's a hint that a lifetime of kicking ass and getting revenge hasn't made him a contented man. What's a grown man supposed to do with his discontent? Kick more ass, of course. It's the circle of life for action heroes.
