Javier Bardem has travelled to Geneva to campaign for actors' rights across the world.
The No Country For Old Men star was joined by Egyptian actress Esaad Younis, British producer Iain Smith and Indian director Bobby Bedi to support a new international treaty on the issue.
The Spanish actor said freeloading off others hurts the nine in ten actors who already struggle to pay the bills.
"People don't have money and movie tickets are sometimes too high, I understand that," he admitted.
"What I don't agree with is the mentality of the people, that to do piracy is fine."
The World Intellectual Property Organisation is currently hosting talks on a draft treaty that is expected to be approved by governments next year.
Javier called for actors to get the same protection as musicians and writers, including the right to earn money from the use of their performance beyond a film's original release.
He also said he wants film tickets to be cheaper to encourage even would-be pirates go to see a film at the theatre once in a while.
When asked if he had ever downloaded a film or song illegally, he replied: "I barely can put on my iPhone."
