Hi, I'm Lauren Zima for About.com, and today we're bringing you the top five war movies of all time. So grab your popcorn, and prepare for battle.Top War Film #5: 'Full Metal Jacket'At number five, it's Stanley Kubrick's 1987 film, 'Full Metal Jacket.' This movie features a tough drill sergeant, the darkness of military brainwashing and the Vietnam War and incredible acting performances. It's known as one of Kubrick's best.Top War Film #4: 'Platoon'This Best Picture winner also covers the Vietnam War. Writer and director Oliver Stone drew on his own experiences for the script. Starring Tom Berenger, Willem Dafoe and Charlie Sheen, the movie explores Vietnam's darkest moments, from seemingly senseless murders and rape to soldiers turning on each other.Top War Film #3: 'The Great Escape'A pure escape story, this film stars the great Steve McQueen and follows prisoners of war escaping a high-security WWII camp through the digging of tunnels. It's been praised for its tormenting story and historical accuracy. But, like many war films, this one's got a tragic ending; many of the prisoners don't escape from the Germans.Top War Film #2: 'Saving Private Ryan'Also about WWII, this Steven Spielberg movie is known for its visuals, especially its violent opening sequence, which depicts the Omaha Beach assault of 1944. Its portrayal of war is extremely graphic, but it's been praised for its accuracy. It tells the story of soldiers in search of Private Ryan, a man they must send home to his mother since his other three brothers have all been killed in action. Stellar acting performances from an ensemble cast including Tom Hanks and Matt Damon make this a must-see.Top War Film #1: 'Apocalypse Now'At number one, Apocalypse Now. This film was a saga to get make, but it was well worth the wait. Francis Ford Coppola's epic had its release date pushed back several times after star Marlon Brando showed up on set overweight, bad weather shut things down, star Martin Sheen had a heart attack during filming and more. There were even real dead bodies on set, though they weren't used in the actual film. In short, the harrowing filming ended up making for an amazingly dark, tortured movie.Those have been your top five war films. For more on movies, go to About.com.
