Actress Jessica Alba says it was because of people who did not believe in her that she became successful.
"People doubted me as an actress and that's something that drove me. I was not going to be pegged as an action-comic-book fangirl," Alba to Vanity Fair magazine, reports femalefirst.co.uk.
Director James Cameron, who gave Alba her big break in TV series "Dark Angel" when she was just 18, said he always knew she would be a star.
"This was a $125 million production and we were resting it on the shoulders of a teenager. She totally stepped up to the plate and didn't fall or falter," he said.
