Marion Cotillard doesn't want her son to be a "great" actor.
Though the 'Inception' star would have no problem with Marcel - her 21-month-old son with partner Guillaume Canet - following in her footsteps, she thinks the best actors have a "failure" or fault within them that allows them to do well, and she doesn't want him to have such problems.
She said: "An actor has a huge failure in him. And this is not a weakness - this can make you strong. But it's deep. Maybe failure is not the right word. Something deep inside which is broken.
"And most of the time I think if you don't have this, you're not a good actor.
"So it's kind of a struggle. I mean, if my son wants to be an actor, it's fine.To be a great actor, you must have this. And I don't want him to have it!"
The 38-year-old beauty admitted she has never asked her own parents - who were both actors - whether they had any concerns about her becoming an actress.
She told Interview magazine: "Ah, it's an amazing job, but my parents never told me anything about how hard the job would be. My parents were actors too. I don't even know if when I wanted to be an actress, they went, 'Oh s**t'. I must ask them."
