Eclipse of Reason: Eclipse of Reason is a 1987 pro-life documentary video directed, filmed, and narrated by Bernard Nathanson, with an introduction by Charlton Heston.  "Eclipse of Reason" is a follow up to Nathanson’s first film "The Silent Scream".  The film is perhaps most known for its controversial depiction of a dilation and evacuation (D&E) abortion.  The subject matter of this film focuses more on the moral implications of abortion.  It served as Nathanson’s call to the women of the world to end the practice of abortion.  This film, as well as "The Silent Scream", was instrumental in the Right to Life Committee's garnering the attention of the United States public regarding the issue of abortion.

Silent Scream (2005 film): Silent Scream (originally known as The Retreat) is an independent, horror film directed by Matt Cantu and Lance Kawas and starring Scott Vickaryous, Melissa Schuman and Shanti Lowry.

Ski Patrol (band): Formed from the ashes of two Sunderland, UK college bands, The Wall and The Debutantes, Ski Patrol was hatched by singer Ian Lowery and guitarist Nick Clift in Brixton, London in the Autumn of 1979.  Inspired by the darkwave and punk-funk sounds and emotions of British post-punk bands like Joy Division, Gang Of Four, A Certain Ratio.  They were also influenced by the Jamaican rhythms and politically charged environment that was their new home, the band set about writing angular, moody songs that fused Lowery's dark lyrical pre-occupations with Clift's ringing, textured guitar chord phrasing.  Joined by fellow North-Eastern transplants Peter Balmer on bass and drummer Bruce Archibald, the band began playing shows on the London live circuit opening for The Carpettes.  By December, they had recorded four songs at Alaska Studios in Waterloo, two of which became their first singles.  "Everything Is Temporary" b/w "Silent Scream" was released in March 1980 on their own Clever Metal label with help from super-indie Rough Trade.  Features in fanzines like Allied Propaganda, Panache, ZigZag and No Class followed.  They quickly gained a regular audience at legendary venues like The Rock Garden in the West End and The Moonlight Club in West Hampstead.

The film depicts the abortion process via ultrasound and shows an abortion taking place in the uterus.
