The new documentary "After Tiller" is guaranteed to stir up heated responses from all sides of the abortion discussion. The film centers on the remaining four doctors who perform late-term abortions -- a controversial practice that even some pro-choice advocates question. The Tiller referenced in the title is Dr. George Tiller, who also performed the operation following pregnancies' 20-week mark and who was killed by an anti-abortion activist in 2009.
"After Tiller" was an official selection for the 2013 Sundance Film Festival. It opens Sept. 20 in New York and Oct. 4 in Los Angeles.
