Seth Rogen, Michael Moore Slam 'American Sniper'

Warner Bros.

Despite its box office success and Oscar nominations, not everyone is a fan of 'American Sniper.'

Despite its box office success and multiple Oscar nominations, not everyone is a fan of American Sniper.

Documentary director Michael Moore shared his views Sunday of the Clint Eastwood movie, starring Bradley Cooper, which follows real-life Navy SEAL sniper Chris Kyle's life on and off the battlefield. "My uncle killed by sniper in WW2," the Fahrenheit 9/11 star tweeted. "We were taught snipers were cowards. Will shoot u in the back. Snipers aren't heroes. And invaders r worse."

Meanwhile, Seth Rogen -- who has faced his own controversy with his comedy The Interview -- jokingly made a dig at the biopic, comparing it to the Nazi propaganda film played in Quentin Tarantino's 2009 movie Inglourious Basterds. He tweeted: "American Sniper kind of reminds me of the movie that's showing in the third act of Inglorious Basterds."

Chris Kyle is considered one of the deadliest snipers in U.S. military history and was killed in early 2013 at a Texas shooting range by a former soldier he was mentoring that had PTSD. Despite Moore and Rogen's views on the film, it landed six Oscar nominations including Best Picture and Best Actor (Cooper).

Not only that, American Sniper has already set box-office records for a January wide release, pulling in an estimated $105 million over the holiday weekend.
