Scarlett Johansson expresses concern for child stars

Scarlett Johansson thinks child stardom can be a "dangerous thing".

The 40-year-old actress - who made her film debut in 'North', the 1994 fantasy-comedy movie - thinks she was "very fortunate" to come through child stardom unscathed.

Speaking to Vanity Fair magazine, Scarlett explained: "Making decisions on your own - like, adult decisions as a kid - it’s a dangerous thing, right?"

The Hollywood actress has seen other child stars struggle to cope with the pressures of fame and success.

But Scarlett is thankful that she "dodged a lot of it".

She said: "I lived through that and also was very fortunate that I dodged a lot of it."
