Hollywood legend Robert De Niro fears he will never helm another movie as directing is so "tough".
The Raging Bull star made his directorial debut with 1993's A Bronx Tale and he stepped behind the camera again to take charge of 2006 thrilled The Good Shepherd.
However, De Niro admits working as a director is much harder than acting, and he fears he might not have the strength to helm any more films.
He tells New York Post gossip column Page Six, "I don't know if I will ever do another movie. If I did five in my life, I would be happy. I might not do three... It's a lot of work... very tough, especially if you care about doing it... It's always about money, about budget. You always have to be fighting them (studio bosses) every second."
