The actor says he wasn't comparing the film to Nazi propaganda.

Seth Rogen has elaborated on a tweet he made about American Sniper.

On Monday, the actor tweeted that the Clint Eastwood drama "kind of reminds" him of of the Nazi propaganda film about a sniper showing near the end of Quentin Tarantino's Inglourious Basterds.

He later clarified that tweet, writing that he liked American Sniper and that he wasn't comparing the two. On Thursday, he issued a statement via Twitter further clarifying his comments. He wrote that he was not implying Sniper was like Nazi propaganda, nor implying that he had anything against veterans.

"My grandfather was a veteran. My comment about the movie was not to have any political implications," the statement read.

American Sniper, which stars Bradley Cooper as Navy SEAL Chris Kyle, opened with a historic $107.2 million over the three-day Martin Luther King Jr. weekend.
