Susan Sarandon gave pictures of herself in the 1970s to British artist Russell Oxley, who used them to paint an acrylic portrait of her character, supposedly from that era. After filming, the canvas went home with Sarandon.
This was the first of two films that featured Jude Law in a role originally played by Michael Caine. The second was Le limier - Sleuth (2007).
Director Charles Shyer was inspired by the skinny suits that the Beatles wore in Quatre Garçons dans le vent (1964) for Alfie's wardrobe and the brown sweater that Alfie wears in several scenes was Jude Law's own.
According to director Charles Shyer, in the shot where Alfie (Jude Law) punches a car windshield, Law actually cracked the windshield. Apparently, the actor wasn't able to put as much effort into punching it until Shyer told him to imagine that it was the paparazzi. As a result, Law punched so hard that a sledgehammer had to destroy the cracked windshield.
Alfie's Vespa is painted blue and white as an inside joke. The colors pay homage to Jude Law's favorite football team, Tottenham Hotspur.
