3Slumdog Millionaire -- Salim
The Heroic Sacrifice:
Despite being hailed as "the feel-good film of the decade" by its own poster, some pretty dark shit goes down in Slumdog Millionaire. For example, at the end of the movie, the protagonist's brother, Salim, decides to stop being a dickhead for once and help out his bro, which involves getting himself killed in a bathtub filled with money.
Which frankly looks like a better game show than Who Wants to Be a Millionaire?"
Jamal, the eponymous slumdog millionaire (spoilers), is in love with Latika, aka that girl he only knew for a few days several years ago. Problem is, Latika has been passed around from gangster to gangster since she was a girl, finally ending up with the one that Salim works for. Seeing his brother answering trivia questions on TV causes Salim to have a change of heart, so he lets Latika go free, despite knowing that this will undoubtedly piss off his boss.
As Latika escapes, Salim makes himself a nice comfy cash bath, lies down inside and shoots the gang leader when he bursts through the door before being pumped full of lead himself.
Just to make extra sure it was completely unusable to anyone, he also peed inside.
Wait a Second ...
While all that "dying in dirty money" stuff provided a nifty visual and moral counterpoint to Jamal's game show victory, there's just one problem: It makes no goddamn sense. Specifically, why couldn't Salim have hot-stepped it out of there alongside Latika?
We'd have been fine with the sacrifice if it had actually helped the girl get away -- he's sacrificing his own life to give her every possible chance. But it doesn't. Unlike her, he was a member of the gang, which should have given him much more freedom to come and go as he pleased -- she has a much better chance of getting out of there if he goes along. Instead, he sends her out without knowing if she's going be stopped at the door by another gangster and horribly punished for trying to escape. Nice one, dude.
Some might say that Salim had to stay so he could kill the gang leader and make sure he didn't go after Jamal and Latika, but we submit that lying in a bathtub (with money or otherwise) is not the most efficient way to kill someone -- unless there's a deleted scene where he spiked his drink with a laxative, Salim had no way of knowing that the leader would be the first to go into the bathroom.
"Whoops, too late."
Seriously, what was Salim going to say if someone else went into the bathroom? "Don't mind me, I'm waiting for someone else"? Salim would have likely been shot just for being a weirdo, and the boss would have survived to send someone after his brother and Latika ... which might still happen with the leader dead, seeing how most of the gang was very much alive at the end of the movie.
Fortunately, the killers were distracted when they had to join the impromptu dance number.
So either Salim did a pretty shitty job at helping his brother, or he simply never stopped being a dick.
2Alien: Resurrection -- Christie
The Heroic Sacrifice:
In Alien: Resurrection, Ripley finds herself fighting those pesky aliens once again, this time as a clone and alongside a group of mercenaries trapped in a spaceship. One of those mercenaries is gun-toting Christie (Warrick from CSI), whose specialty is making extremely unlikely shots by ricocheting his bullets on just the right angles.
Because boastful badasses always have the best luck in the Alien franchise.
At one point, the troupe have to make their way up a rickety space ladder to escape certain death -- unfortunately, one of them, Vriess, is wheelchair bound, and the ship doesn't appear to have any working access ramps. Christie is nice enough to give Vriess a lift, strapping him reverse-piggyback-style, but as the two ascend to safety, they are suddenly attacked by an alien who manages to get a grip on Christie's foot. As they struggle with the alien, the situation is reversed, with Vriess hanging from the ladder and Christie piggybacking on his back.
"It was your turn anyway, man."
When the alien is finally shot in the face, Christie is left with a pile of dead meat still clinging to his foot -- and since Vriess is slowly losing his grip from all the weight, Christie sees no other choice ...
"Welp, suicide ahoy."
... and cuts himself and the alien loose, saving Vriess but dying in the process.
Wait a Second ...
Let's for a second ignore the fact that the expert marksman repeatedly missed the massive alien climbing toward him -- maybe he was just thrown off by the fact that there was nowhere to bounce his bullets. There's an even bigger problem in this scene, namely the fact that the "grip" on Christie's foot looks like this:
This is why you should always spray your boots with Pam before fighting aliens in space.
That seriously looks like something they had to glue to the actor's boot because otherwise it'd just fall off by itself. Christie couldn't shake that off? Or kick it away with the other leg? Or just tilt his foot slightly and let gravity do the rest? Remember that the alien is dead now, so it's not like it can put up any resistance.
"Yay, I survived a vicious alien attack. What, it's slightly touching my foot? NOOOOOO!"
The alien did manage to burn Christie's face by spitting on him, but clearly alien saliva isn't as acidic as their blood, otherwise the aliens could have just loogied their way out of their cell earlier (they had to kill one of their own and use his blood to eat through the steel). Except for the instantaneous scar, Christie seemed just fine, and it didn't look like the acid was eating through his skull or anything.
Unlike Ron Perlman's character, who looks exactly like that all the time.
And this actually gives us the only rational explanation for Christie's behavior: He knew that his second career as a male model was over, and decided that life wasn't worth living as a cripple (to which Vriess probably said "Hey, fuck you.")
