Hollywood actor Sean Penn is taking Argentina's side in the Falklands dispute.
Penn met Argentine President Cristina Kirchner in Buenos Aires today and then urged Britain to join UN-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 British, and is increasing its military defences ahead of the 30th anniversary of Argentina's failed effort to seize the islands.
Penn says diplomacy is the only solution.
