Actor Sean Penn is taking Argentina's side in the Falkland Islands dispute.
Penn met with Argentine President Cristina Kirchner on Monday and then urged Britain to join U.N.-sponsored talks over what he called "the Malvinas Islands of Argentina."
Penn says "the world today is not going to tolerate any ludicrous and archaic commitment to colonialist ideology."
Britain has refused to negotiate as long as Falklanders want to remain part of the British realm, and is increasing its military defenses ahead of the 30th anniversary of Argentina's failed effort to seize the islands.
Penn says diplomacy is the only solution.
