- When Mario Monicelli's segment, "Renzo e Luciana", was cut, producer Carlo Ponti offered to finance the Monicelli film as a full-length feature on its own. This was never realized. This segment was apparently cut because Monicelli promised to deliver a "major American star" but failed in this endeavor, thus his film became cast with mostly unknowns. When the film premiered at Cannes, it was jeered by critics and filmmakers after they became informed of the news about Monicelli's unjustly removed segment.
- Federico Fellini's segment, "Le tentazioni del dottor Antonio", was his first work in color. It and Fellini's contribution to L'amore in città along with his co-directed "Variety Lights" are the "1/2" alluded to in the title of 8½.
