Director Rob Marshall interviewed Loren for an onstage career retrospective at the Dolby Theatre in Los Angeles, running through her Italian acting work, her transition to Hollywood and her later films.
The 80 year old discussed the male co-stars she encountered throughout her career, telling Marshall that Cary Grant was a "special person, a great actor, absolutely incredible as a person" and Peter Sellers was a "very melancholic person. He would light up only when the director said action".
She added that she liked Clark Gable, "But he had a watch and it rang every evening at five. When it rang, he would leave without saying goodbye."
However, Loren also made it clear she was not a fan of Marlon Brando, simply shrugging when his name was brought up. They co-starred in A Countess of Hong Kong and she recalls the Godfather star keeping her and Charlie Chaplin waiting, so Chaplin reprimanded him for it.
Modern Family star Sofia Vergara and Loren's son Edoardo Ponti also took to the stage to praise Loren, and Vergara's boyfriend Joe Manganiello and actress Michelle Monaghan were in the audience.
Following the tribute, festival organisers screened a restored version of the actress' 1964 comedy Marriage Italian Style and short film The Human Voice, which was directed by her son.
The Afi Fest will close on Thursday evening (13Nov14).
