Washington, Mar 3 : Penelope Cruz must have won the Oscar for the Best Supporting Actress this year, but she has admitted that she still feels "insecure" while doing a new film.

The `Vicky Cristina Barcelona' star has said that despite so many years of being an actress, she continues to be a "bundle of nerves" when she's on the set.

"I''m always insecure on the set no matter what," Fox News quoted Cruz as saying.

She added: "When you''re working with Woody Allen you know that you can trust the person that you''re working with and if he doesn''t like something he will tell you, but he''s honest and that''s what counts for me."

The Spanish starlet has faced a lot of criticism over her poor pronunciation of the English language, but she claims that the negativity has helped her achieve what she is today.

She said: "Sometimes invalidations like that ... I have to keep climbing mountains and sometimes there are some things that are better not to listen, it''s better not to engage in those debates. So could you work in America if you have an accent? Yes, you can. And that has been changing in the last 10 or 15 years; it was much harder before." (ANI)
