The Kill Bill actress, who suffers from Asperger's Syndrome, admitted that she almost ruined her acting career because she was too nervous to promote her films.
Hannah told The Times: "I never went on talkshows, never went to premieres. Going to the Academy Awards was so painful for me. I'd almost faint just walking down the red carpet. I was so socially awkward and uncomfortable that I eventually got blacklisted.
"Studio executives would call me but I'd be too shy to call them back. So after a while a couple of studios literally told my manager that I was blacklisted."
The Splash star also insisted that she would never put her career before her personal life.
She added: "If something in my personal life comes up that moves me - whether it's because my father was ill, or because I want to spend time with my boyfriend - I will prioritise that over taking a movie part. That's the way I've been throughout my life."
Hannah recently claimed that she was strange and anti-social as a young girl.
