Al Pacino Dodges Marriage Question While Girlfriend Watches Closely

Just when Al Pacino thought he was out of marriage talks, paps in Argentina pulled him right back in ... with his girlfriend standing right next to him!

The Godfather, and his Argentinian gf, Lucila Sola, had no trouble answering questions in Buenos Aires -- until one photog went and asked if he was ever going to marry her?

You gotta see Al's reaction -- half Sonny Wortzik frantic stammering, half Michael Corleone defusing a GF ... who's clearly very interested in his answer.
