''This Means War'', starring Creator/ChrisPine and Creator/TomHardy, directed by [=McG=] and produced by Creator/WillSmith, is a 2012 action romantic comedy about two CIA agents who accidentally start dating the same girl.

The two agents, Tuck (Tom Hardy) and FDR (Chris Pine) are scouting out a party for a target. This introduces us to the two main characters and their dynamic, which is a typical but adorable pair of good friends. Tuck is much more polite and sweet while FDR is roguish and impulsive. Their targets are two brothers and when a fiery shootout hits, one of the brothers is accidentally killed, causing the other, Heinrich (Til Schweiger), to swear revenge on the two friends.

Meanwhile, a lonely woman named Lauren (Creator/ReeseWitherspoon) has gotten tired of the single life and her best friend Trish (Chelsea Handler), makes her a profile on a dating site. Similarly, Tuck has had little luck in love as he is divorced and has a child to take care of and so he decides to try the same dating site. He and Lauren meet up on a blind date and hit it off while FDR hangs out in a video store nearby just in case the date goes south and Tuck needs an escape. However, Lauren goes to the video store and FDR, clueless that itís the same girl Tuck had just gone out with, becomes interested in her as well. Tuck and FDR meet up later at their office only to discover they are dating the same girl. Both men offer to break it off with her because they are friends and do not want to lose their friendship over a girl, but their pride gets the better of them and it becomes a competition to see who Lauren chooses. As their tempers flare, their friendship starts to fall apart as they get more and more aggressive about trying to get Lauren to fall in love with one of them. All the while, the enraged Heinrich is closing in and looking for a way to hurt the boys for the death of his brother.

!! This film contains examples of:

* ActorAllusion: At two different parts of the movie, FDR claims to be [[Film/StarTrek captain of a cruise ship]]
** It's the first reply that justifies the trope: [[spoiler:"Permission to come aboard, Captain?"]]
** Nana's been taking care of FDR after he lost both parents at a young age. [[Film/SpiderMan Hardly the first time either.]]
* AgentsDating: The movie is pretty much centered around this. Lauren decides to have sex with two different spies who are pursuing her, to see which one of them is better in bed. After they found they've been sleeping with the same woman, they wage an epic battle against one another.
* AllGirlsWantBadBoys: Accidentally implied with [[spoiler: Lauren's choice to date FDR instead of Tuck.]]
* AmicablyDivorced: Seems to be the case between Tuck and his ex. She's not his biggest fan, but she isn't nasty to him at any point when she comes to pick up their son. It is further enforced by [[spoiler: her agreeing to go out to dinner with him after Lauren chooses FDR.]]
* AndTheAdventureContinues: FDR and Tuck talking about FDR's encounter with Tuck's wife (before the couple met) as they begin their next mission.
* BashBrothers: FDR and Tuck.
* BelligerentSexualTension: How Lauren and FDR's relationship starts out.
* BettyAndVeronica: Lauren is torn between the sweet Tuck and the flirtatious FDR.
* BigDamnHeroes: [[spoiler: After Heinrich kidnaps Lauren and Trish, the boys steal a Jeep and go after them, completely ignoring Heinrich's demand for them to meet him at an abandoned warehouse.]]
* BottomlessMagazines: Averted. Tuck runs out of ammo in two fight scenes. Both times, FDR passes him a magazine. The second time, he scolds Tuck for not carrying extra magazines like he does.
* BoyfriendBluff: How Lauren and FDR eventually reconcile their differences enough to actually date.
* BullyingADragon: The over-aggressive father at Tuck's son's karate class. Seriously, who talks shit to Tom Hardy about his kid?
* TheCharmer: FDR. Tuck is gorgeous, but not as flirtatious as FDR so he doesn't get noticed as much.
* ChekhovsSkill: Lauren's extensive knowledge of consumer products pays off when [[spoiler: when she tells the boys to shoot the headlamps of a (otherwise bulletproof) car, thereby triggering the airbags.]]
* CockFight: Tuck and FDR try to avoid this for the most part, but the more emotionally invested they become in Lauren, the more they argue [[spoiler: and eventually get into a fist fight.]]
* CurbstompBattle: When Tuck decides to try out paintball, he completely demolishes everybody on the field [[OneManArmy all by himself]].
* CynicismCatalyst: The death of Heinrich's brother sets him off on revenge.
* DaChief: Played, oddly enough, by ''Angela freaking Bassett.''
* DeadpanSnarker: Both the boys, but FDR moreso than Tuck.
* DidNotGetTheGirl: [[spoiler: Tuck. Though he reconciles with his ex and they are together at the end.]]
* DistressedDamsel: [[spoiler: Lauren when Heinrich catches up to her. Trish too because she happens to be in the same car at the time of the kidnapping.]]
* DuelingStarsMovie
* EnhanceButton: Played straight when FDR has one of the techs do magic enhancing to reveal the bad guy stalking Tuck.
* {{Expy}}: FDR is unnervingly similar to Chris Pine's portrayal of Jim Kirk in J.J. Abrams' ''Star Trek'' reboot.
* FakeOutMakeOut: Lauren pulls one with FDR to make her ex jealous. It works. Hilariously.
* {{Fanservice}}: Chris Pine getting shirtless, and later naked, for the girls (and some guys); Reese Witherspoon in her undies for the guys (and some girls). Though Tom Hardy's arms in general make him borderline fanservice too.
* FreudianExcuse: [[spoiler: FDR's parents died in a car accident when he was a kid, and "he was never the same since."]]
* GenreSavvy: The boys have enough sense to know [[spoiler: not to meet Heinrich at the location he suggested to get Lauren back and instead hijack a Jeep and grab her en route.]]
* GroinAttack: Completely accidental, but Lauren shoots Tuck in the crotch with a paint gun.
* HandsomeLech: FDR, in spades.
* HeadTiltinglyKinky: The agents watching FDR and Lauren imply that the two put on quite a show.
* HeterosexualLifePartners: Tuck and FDR.
* HiddenDepths: Late in the film, Trish [[spoiler: while helping her son with something, tells Lauren how much she loves her husband, and that she shouldn't choose the better man, but rather should pick the man who makes her a better woman.]]
* HomosocialHeterosexuality: Pretty much the entire plot.
* INeedAFreakingDrink: When Lauren believes that Tuck and FDR are meeting for the first time, she [[INeedToGoIronMyDog makes some lame excuse to leave for a moment]], and then asks them to order her a drink. Something in a shot.
* JerkWithAHeartOfGold: FDR comes across as this to Lauren. The viewers know he's a lot sweeter than he lets on, but he doesn't show his nicer side to Lauren until later in the movie.
* KarmaHoudini: FDR and Tuck. They break into Lauren's apartment, tap her phone, set up cameras everywhere, and place trackers on her. Neither of them face serious consequences for their actions.
* LettingTheAirOutOfTheBand: During a date with Lauren, FDR is trans-darted by Tuck, and the background music ("Sabotage" by TheBeastieBoys) starts getting slower, and slower, and slower until finally FDR falls unconscious.
* LoveTriangle: The entire plot of the film, basically.
* MadeOfExplodium: During the chase scene [[spoiler: the boys shoot out the SUV's headlights, detonating the airbag and causing the SUV to slam into a stationary object and blow right the Hell up in a fiery explosion.]] Ford Exploder indeed.
* MeaningfulEcho: [[spoiler: Would you like to have dinner... as a family?]]
** IronicEcho: [[BullyingADragon Pain is weakness leaving the body.]]
* MrFanservice: Tom Hardy. Chris Pine. In one movie. ''AT THE SAME TIME.''
* NoodleIncident: Whatever happened in Kandahar, mentioned briefly during a fight.
** Also, whatever happened in Bangladesh.
* TheObiWannabe: Lauren most likely wouldn't be in this mess if she weren't following Trish's horrible excuse for guidance.
* OnlyKnownByInitials: FDR Foster, obviously. Also somewhat of a ShoutOut to former U.S. President Franklin Delano Roosevelt, who was also known by that moniker (his full name is "Franklin Delano Roosevelt Foster"... you'd call yourself FDR too).
* PlayingDrunk: The boys try this to catch a bad guy who knows Heinrich.
* PairTheSpares: [[spoiler: Tuck and his ex get back on good terms by the end of the film after Lauren chooses FDR.]]
** Alternately, in one of the alternate endings, [[spoiler: FDR gets back with his flight attendant female friend... and her female co-worker.]]
* ShirtlessScene: Chris Pine has a couple, but oddly, Tom Hardy does not.
* SpotlightStealingSquad: Trish, played by Chelsea Handler, takes over every scene she's in and makes it hard to realize Lauren is even there. This is mostly due to Handler's outrageously over-the-top lines.
* StalkerWithACrush: Both of the men vying for Lauren dance into this trope.
* UptightLovesWild: [[spoiler: Ultimately reflected with Lauren's choice.]]
* WasItAllALie: [[spoiler: Lauren doesn't know what to think when she finds out Tuck and FDR are best friends.]]
