5. Bo Derek in 10 (1979)
Once 10 was released in '79, Dudley Moore wasn't the only one obsessed with Bo Derek. That gold bikini—we don't even have words. Derek's iconic swimwear made women run out, buy bikinis and tightly braid their hair. The famous scene of her running down the beach undoubtedly made her an overnight star, even earning her a "Best New Actress" nomination at the Golden Globes.
