Mix a "comedy machine" with a novice director. Add a shutdown threat, rotating robbers and terrifying stunts to home in on a ho-ho-ho holiday megahit.

This box office titan took action movies to the next level, decked out with a relatable hero, a humorous rewrite and a well-played “yippee-ki-yay.”

Crunch the numbers, then make way for a chubby T. rex and visual effects bad boys. This box office heavyweight disrupted the way movies are made.

It took a young team's blood, sweat and tears — and a triple-threat visionary — to make this bloodless yet scarily influential horror masterpiece.

A rickety script, tight timeline and effects issues almost busted this comedy. But thanks to Dan Aykroyd and company, the slimy shenanigans took off.

Life is like a box of chocolates — or a charming script unearthed by chance. Despite casting and budget woes, this humble tale became a '90s classic.

A hard-driving director, stressed crew, great expectations — and a tiny budget — made for a difficult birth in the case of this mother of all sequels.

Stepping on toes and tangling with rejection, the women behind this "girl's movie" touched millions despite co-star tension and a meager budget.

A painfully tight suit and budget, a passionate European auteur and on-set tensions fueled this blockbuster takedown of cutthroat corporate America.
