The Adventures of Captain Marvel showcases one of the earliest film examples (which makes sense, given that it's the first-ever superhero film) with the titular Captain Marvel. Throughout the 12-episode serial, the Captain lifts enormous stone columns, large fallen trees, elevator cars, and other feats of strength, to the point that he ends some of his fistfights with criminals by casually slapping them.
The Xenomorphs appear to have this, given that one easily overpowers Brett in Alien, and a group effortlessly pulls open automatic doors barring them from their prey in Aliens. Justified a bit as their bodies have exoskeletons and are biomechanical in nature, making them much stronger than the average human. They can even overpower Yautja, with one Xenomorph impaling a Yautja warrior and lifting him up into the air with its tail. The Xenomorph Queen is the strongest, being able to rip android Bishop in two like wet tissue paper and match Ripley in a Power Loader. The Facehuggers are also dreadfully strong for their size — in Aliens, it takes the combined effort of Hicks, Vasquez and Gorman just to get one off of Ripley before it can impregnate her.
The M-56 Smart Gun in Aliens is already a hefty piece of equipment, weighing in at 18 kilograms (or 36 pounds), and yet Operator Mark Drake is able to effectively and accurately operate said heavy-weapon and retreat at a brisk pace while wearing 4-kilograms (or 8 pounds) of chest plate armor, while also carrying a fully-loaded M-240-A Flame Unit, which adds yet another 2 kilograms (or 4 pounds) to his already considerable encumbrance. Drake sure is one tough customer, being able to briskly maneuver and effectively fight while weighed down by 24 kilograms (or 48 pounds) of weapon and armor at all times.
The Engineers, as seen in Prometheus, are super-strong thanks to their size and biology; we see one Engineer rip the android David's head off with one arm and use it to beat Weyland to death. In the Prometheus tie-in comic Predator: Fire and Stone, one Engineer easily fights the Yautja Ahab, snapping his arm like a breadstick and tossing him around — Ahab has to use his gadgets to weaken the Engineer in order to kill it.
The eponymous hero of the Baahubali duology can lift 100-pound statues of solid gold without breaking a sweat.
Blade Runner: Nexus-6 Replicants are built to be far more durable and stronger than human beings, at the cost of a reduced lifespan. In the climax, Roy Batty lifts up Deckard's entire body weight using only one hand to save Deckard's life.
The Replicants' strength is shown in even greater detail in Blade Runner 2049, as the Nexus-9 Replicant protagonist K at one point busts through a wall like Kool-Aid Man◊ and the willowy Luv effectively overpowers the protagonist at several points. However, while Nexus-9 Repiclants are strong, they're still not that much more durable than normal humans and are still vulnerable to bleeding to death, getting shot and drowning, thus making them Glass Cannons in general.
Riddick has super-strength as part of the benefits of being a Human Alien from a high-gravityDeath World. Combined with the savagery and brutality that he displays in combat, he tends to shred through his opponents like they're made out of tinfoil. Of course, in retrospect, it makes you wonder how a simple locked door could stop Riddick in Pitch Black.
The Necromongers display prodigious levels of physical strength, especially those in the higher ranks like Vaako and the Lord Marshall. Again, it's been pointed out that the Necromongers hail from a heavy-gravity world, and they make use of gravity-based energy weapons along with gravity engines and drives for their ships and vehicles.
The most prominent example are the Kryptonians, namely Clark Kent a.k.a. Superman — just like in the comics, Clark's strength fluctuates wildly in the films, resulting in a great deal of Power Creep, Power Seep. In Man of Steel, Clark is very strong, being able to lift a school bus out of a lake as a teen and hold up a oil rig as an adult (though he definitely struggles with the latter). Once Clark fully realizes his powers, he's much more effective, with his strength able to smash straight through buildings and make a Kung-Fu Sonic Boom with his fists. Interestingly, other Kryptonians such as Faora, Nam-ek and Zod can easily match Clark in strength, giving him a harder time throughout the movie — however, Superman is still a good deal stronger them (likely due to being exposed to Earth's sun for longer), as he can Neck Snap Zod despite the latter's Nigh-Invulnerability. In Batman v Superman: Dawn of Justice, Clark's strength is more erratic, as he can pull an ocean liner through ice◊ but is forced down onto one knee◊ when lifting a piece of a space shuttle (approximately 165000 pounds-75000 kg), though in the latter case, he's likely being careful as to not hurt the astronauts inside. In the Final Battle, Clark is again matched — this time by Doomsday, who mostly overpowers him, requiring Wonder Woman to help him out in the fight. In Justice League (2017), all bets are off, and Supes is much stronger than he was presented as in the previous films, now able to effortlessly carry a huge building (which is likely much heavier than the oil rig and definitely heavier than the shuttle). In his resurrection scene (featured more prominently in Zack Snyder's Justice League), he also easily overpowers Wonder Woman, Aquaman, and Cyborg, despite the first two actually being closer in strength to him in the comics.
Arthur Curry a.k.a. Aquaman, due to being a human-Atlantean hybrid, has a body and physical capabilities far greater than any normal human. In Aquaman (2018), he's shown to be able to lift a submarine (likely over 48,000 tons, though he's using hydrokinesis here and is much stronger in the water than on land) from the ocean. Aquaman is also able to smash extremely durable materials like an NSA drone, Blank Manta's Powered Armor, and even send Steppenwolf flying with his mother's trident. In the climax of Zack Snyder's Justice League, Arthur is strong enough to impale a battered Steppenwolf through the chest from behind and actually lift him up with the trident.
Technology can drastically boost strength — see Batman's Powered Armor, which helps him fight (a kryptonite-poisoned) Superman, and Cyborg, whose tech gives him to strength to knock back a Humvee and even help Superman pry apart three Mother Boxes.
Elysium: Aside from being able to rip off the heads from droids and throw people around like dolls, the Exosuits increase the user's physical performance dramatically. They move more quickly than the average combatant, and Kruger is able to leap a great distance and height using his Exosuit. Max is able to rip himself from a gurney and pretty much pulverize Crowe into the floor of the Armoury before throwing him like a shotput.
Ghost Rider (2007) gives an impressive visual example of super-strength violating the laws of physics, as the Rider snares a helicopter with his chain and pulls it down. Unless he's heavier than a helicopter, tugging on the chain should have launched him toward it. Whatever demonic powers were at work somehow knew which he was trying to achieve.
Godzilla gives two examples; Godzilla himself, able to throw kaiju of equal proportions over his head, and Titanosaurus, the only kaiju in the entire series to lift Godzilla by the head using only his own head and neck.
Highlander: Though it isn't specified, the Immortals appear to have this along with Immortality. Connor MacLeod is able to cut through a concrete pillar with his Cool Sword, and Big Bad Kurgan impales a man with his sword and lifts him up by the hilt before throwing him across an alley.
Indestructible Man: After his resurrection, Butcher Benson is strong enough to lift a car and rip a steel safe apart with bare hands.
Obviously the larger dinosaurs from the Jurassic Park franchise are much stronger than people, but they are also shown to be much stronger than their real-life counterparts as well. This is most noticeable for Rexie, the Spinosaurus, and especially the Indominus.
King Kong is a classic example, being a gigantic ape who can snatch biplanes out of the air and crush them as well as overpower and kill multiple dinosaurs who attack him on Skull Island. In Kong: Skull Island, Kong swings a ship's anchor chain around as a Improvised Weapon, and in Godzilla vs. Kong, he's even able to stagger and down Godzilla with his blows.
Fezzik in The Princess Bride has great strength, most notably shown during Westley's first encounter with the giant, in which Fezzik gives Westley a warning shot by throwing a boulder at a rock near Westley's head so hard that it powderizes. Fezzik then picks up another enormous boulder in one hand, nonchalantly chucking it over his shoulder when they decide to fight in hand-to-hand combat.
The Turtles have this in Teenage Mutant Ninja Turtles (2014). Donnie is able to throw Raph with enough force to bash in a Humvee and send it rolling down a hill and flip another truck over with only his bo staff himself. Earlier, when hyped up on adrenaline, they all break through their unbreakable glass cages.
Thirst (2015): The alien displays how strong it is by throwing one of the cast through the air and into a fence, which breaks to pieces on impact.
Yello Dyno from Tricky People can rip locked safes open with little to no effort.
David in Unbreakable can rip car doors off and lift over five hundred pounds (as seen in a Deleted Scene). It's unclear what his maximum potential is, as lifting anything heavy requires great effort, and he never fails at lifting anything. It's hinted that David's only limits are those that he puts in his own mind.
Underworld (2003): In Underworld: Evolution, Marcus pulls a helicopter out of the air by pulling a chain hanging from it. It's possible that Marcus is gripping the cave floor with his clawed feet, but it's not shown.
We Are the Night: The vampires get this. Although appearing to be just ordinary women, they can toss around much larger men with ease and kill them using only their bare hands (via Neck Snap when not draining their blood).
