She has starred in the films "At Close Range" (1986), "Some Kind of Wonderful" (1987), "Chances Are" (1989), "Fried Green Tomatoes" (1991) and "Benny & Joon" (1993).

Nine (2009 live-action film): Nine is a 2009 romantic musical drama film directed and produced by Rob Marshall and written by Michael Tolkin and Anthony Minghella.  The film is an adaptation of the 1982 musical of the same name, which in turn is based on Federico Fellini's semi-autobiographical 1963 film "8½".  In addition to songs from the stage musical, all written by Maury Yeston, the film has three original songs, also written by Yeston.  The ensemble principal cast consists of Daniel Day-Lewis, Marion Cotillard, Penélope Cruz, Judi Dench, Fergie, Kate Hudson, Nicole Kidman, and Sophia Loren.

Maria Antonietta Beluzzi: Maria Antonietta Beluzzi (26 July 1930 – 9 August 1997) was an Italian actress who appeared in a number of films in her native country.  She is probably best known as the large and huge-breasted tobacconist in Federico Fellini's "Amarcord", whose sexual arousal by the male teenager protagonist ends with ironic results.  This casting occurred ten years after Fellini first cast her in an uncredited role (as a screen test candidate for "La Saraghina") in "8½".

Nine (musical): Nine is a musical, initially created and written by Maury Yeston as a class-project in Lehman Engel's BMI Music Theatre Workshop in 1973.  It was later developed with a book by Mario Fratti, and then again with a book by Arthur Kopit, music and lyrics by Maury Yeston.  The story is based also on Federico Fellini's semi-autobiographical film "8½".  It focuses on film director Guido Contini, who is dreading his imminent 40th birthday and facing a midlife crisis, which is blocking his creative impulses and entangling him in a web of romantic difficulties in early-1960s Venice.

Alex in Wonderland: Alex in Wonderland is a 1970 American comedy-drama film directed by Paul Mazursky, written with his partner Larry Tucker, starring Donald Sutherland and Ellen Burstyn.  Sutherland plays Alex Morrison, a director agonizing over the choice of follow-up project after the success of his first feature film.  The situation is similar to the one Mazursky found himself in following the success of "Bob & Carol & Ted & Alice" (1969) and he casts himself in a role as a new-style Hollywood producer.  His daughter Meg Mazursky appears as Amy, one of Morrison's daughters.  Noted teacher of improvisational theater Viola Spolin plays Morrison's mother.  The film also features cameo appearances by Federico Fellini and Jeanne Moreau, and seems to be inspired by their work.  In particular, Fellini's "8½" (1963), about a film director who's artistically stuck, is referenced.  Moreau sings two songs on the soundtrack, "Le Vrai Scandale" (for which she wrote the words) and "Le Reve Est La."
