She spent so much time isolated in pediatric wards that she struggled to make friends at school until her health stabilized.

Alba learned to swim before she could walk and became a certified PADI scuba diver at age nine. This lifelong underwater skill landed her breakout role on the 1995 series Flipper in Australia, where she performed all her own free-diving stunts alongside marine biologists and wild dolphins.

Director James Cameron auditioned over 1,200 actresses for the genetically engineered supersoldier Max Guevara in Dark Angel.

In a hilarious surprise twist, the geneticists also discovered she shares a distinct segment of identical DNA with talk show host Jimmy Kimmel.

At age 15 while filming Flipper in Queensland, Australia, Alba received terrifying phone threats before mysteriously vanishing from the studio lot.
