Robin Wright fears she will not be able to ''grow old gracefully'' on screen.

The 48-year-old star - who has sons Dylan Frances Penn, 23, and Hopper Penn, 21, with ex-husband Sean Penn - is concerned audiences will not want to see older actresses on camera in the near future which could leave her out of work.

She told The Guardian newspaper: ''I'm worried that the audience is being conditioned. That's my real fear. Because if they don't want to see wrinkles on the screen, if they actually fear looking at them, then it's only going to get worse. Those of us who don't want to shoot up and cut and sew, we're just not going be cast.

''I don't know, it's not good. Maybe we're already past that point. I just pray I can keep working. I just pray I grow old gracefully.''

Robin plays a washed-up version of herself in upcoming movie 'The Congress' but she insists the part is not accurately based on her life.

She added: ''This movie is not autobiographical in any way.

''Other than the fact that it uses my name and the roles that I did. And other than the fact that I will always be known as Buttercup and Jenny.''
