This Means War was previously scheduled for wide release on February 14, but 20th Century Fox postponed its opening to February 17, 2012, in order "to avoid a head-on confrontation with" Screen Gems' The Vow, which had been "expected to dominate" the box office on Valentine's Day.
During its first weekend ending February 19, it opened at #5 behind Safe House, The Vow, Ghost Rider: Spirit of Vengeance, and Journey 2: The Mysterious Island with $17.4 million from 3,189 locations. Based upon 165 reviews, it received a 26% "rotten" score on Rotten Tomatoes, with an average score of 4.3/10 with the consensus saying, "A career lowlight for all three of its likable stars, This Means War is loud, clumsily edited, and neither romantic nor funny." On Metacritic, the film holds a rating of 31 out of 100, based on 36 reviews, indicating "generally unfavorable reviews".
