Context: Richie Rich (sometimes stylized as "Ri¢hie Ri¢h") is a 1994 American comedy film directed by Donald Petrie, based on the Harvey Comics cartoon character of the same name created by Alfred Harvey and Warren Kremer.  The film stars Macaulay Culkin, John Larroquette, Edward Herrmann, Jonathan Hyde, and Christine Ebersole while Reggie Jackson, Claudia Schiffer, and Ben Stein appear in cameo roles.  Culkin's younger brother, Rory Culkin, played the part of young Richie.  While in theaters, the film was shown with a Wile E. Coyote and The Road Runner cartoon called "Chariots of Fur". Mac and Me is a 1988 American science fiction adventure film co-written (with Steve Feke) and directed by Stewart Raffill.  The film is about a "Mysterious Alien Creature" (MAC) that escapes from nefarious NASA agents and is befriended by a boy who uses a wheelchair due to paraplegia.  Together, they try to find MAC's family, from whom he has been separated.  The film stars Jade Calegory (in his only film appearance), Christine Ebersole, Jonathan Ward, Katrina Caspary, and Lauren Stanley. My Girl 2 is a 1994 American comedy-drama film and a sequel to "My Girl" (1991) starring Anna Chlumsky, Dan Aykroyd, Christine Ebersole, Jamie Lee Curtis, Richard Masur, and Austin O'Brien.  A book based on the script was written by Patricia Hermes in 1994. Grey Gardens is a musical with book by Doug Wright, music by Scott Frankel, and lyrics by Michael Korie, based on the 1975 documentary of the same title about the lives of Edith Ewing Bouvier Beale ("Big Edie") and her daughter Edith Bouvier Beale ("Little Edie") by Albert and David Maysles.  The Beales were Jacqueline Kennedy's aunt and cousin, respectively.  Set at Grey Gardens, the Bouviers' mansion in East Hampton, New York, the musical tracks the progression of the two women's lives from their original status as rich and socially polished aristocrats to their eventual largely isolated existence in a home overrun by cats and cited for repeated health code violations.  However, its more central purpose is to untangle the complicated dynamics of their dysfunctional mother/daughter relationship. "Single Women" is a song, written by "Saturday Night Live" writer Michael O'Donoghue.  The song, which depicted a number of women looking for love in a singles bar, was originally performed during an "SNL" sketch by Christine Ebersole on the October 10, 1981 broadcast.  The song later provided a top-ten country hit for Dolly Parton from her 1982 "Heartbreak Express" album.  Released as the album's first single in February 1982, it reached number 8 on the U.S. country singles chart in April 1982.  The Parton version of the song featured somewhat reworked lyrics, as RCA requested she eliminate the drug references, fearful that they would cause the song to meet resistance on country radio.  The song later inspired a 1984 TV movie titled "Single Bars, Single Women", starring Tony Danza and Jean Smart, which was produced by O'Donoghue.  An abbreviated version of Parton's recording of the song was used as the movie's theme song. Grey Gardens is a 28-room house at 3 West End Road and Lily Pond Lane in the Georgica Pond neighborhood of East Hampton, New York.  The lives of its residents were chronicled in the "Grey Gardens" 1975 documentary, 2006 Broadway musical, 2009 television movie, and numerous other books and documentaries. Christine Ebersole (born February 21, 1953) is an American actress and singer.  She has appeared in film, television, and on stage.  She appeared on Broadway in the musical "42nd Street", winning a Tony Award, and appeared both Off-Broadway and on Broadway in the musical "Grey Gardens", winning her second Tony Award.  She has co-starred on the TBS sitcom "Sullivan & Son", where she played Carol Walsh. The Outer Space Connection is a 1975 documentary film produced by Alan Landsburg, directed by Fred Warshofsky and narrated by Rod Serling.  This documentary was the last in a trilogy of ancient astronaut documentaries produced by Landsburg.  This film was one of the last projects that Rod Serling worked on prior to his death in 1975. Maureen Moore (born August 12, 1951 in Wallingford, Connecticut) is an American actress.  Debuting on Broadway in 1974's revival of "Gypsy" as Dainty June, Moore has had a long career on stage (also appearing in some films and television).  Although she has been cast in a number of major Broadway roles, Moore has notably carved out a niche as standby for the biggest stars on Broadway in such demanding starring roles as Edie/Edith in "Grey Gardens" (for Christine Ebersole), Mama Rose in "Gypsy" (for Bernadette Peters) and Norma Desmond in "Sunset Boulevard" (for Elaine Paige). Black Sheep is a 1996 comedy film directed by Penelope Spheeris, written by Fred Wolf and starring Chris Farley and David Spade.  The film portrays a political contest in which a candidate for Governor of Washington deals with unwanted, incompetent, and publicly embarrassing help from his brother.  The film also stars Tim Matheson, Christine Ebersole, and Gary Busey.  Chris Owen and Wolf have cameo appearances, and Farley's real-life brothers Kevin and John appear as two security guards at an MTV Rock the Vote concert.  It was the second collaboration between Farley and Spade, as well as the duo's second film with Paramount Pictures, following the 1995 film "Tommy Boy".  The film grossed $32.3 million during its U.S. theatrical run.
