The Martians — Mars Attacks! (1996)

Big exposed brains. Bulging eyes. Flying saucers. And that unforgettable "Ack! Ack! Ack!" These Martians showed up on Earth looking like the aliens from an old-school sci-fi nightmare, then proceeded to turn the entire planet into a giant practical joke. They blast humans into skeletons, mock world leaders, and seem to enjoy every second of the destruction. There's something wonderfully ridiculous about how cruel and cartoonish they are. Unlike the silent Xenomorph or the disciplined Predator, these invaders are loud, mischievous, and completely unpredictable. Their strange appearance and cackling voices make them impossible to confuse with any other alien. But can a gang of gleeful troublemakers defeat the more serious contenders? If chaos counts for anything, the Martians are coming in hot.
