Hollywood star Natalie Portman is her own worst critic and is brutally self-conscious about her acting performances.

The actress confesses to analysing her work and finds faults in almost every film she has made, with her insecurity peaking following her performances as Queen Amidala in the Star Wars prequels.

She says, "I often feel insecure and don't believe in myself. I have a thousand doubts a day.

"Everyone hated my performances in Star Wars and thought I was a terrible actress."

"Almost every movie has a scene that stands out to me as something I messed up on. It drives you to do better, too, when everyone's saying you're terrible, or you feel like you're terrible." (IG/TG/MT)
