The film is Carr-Wiggin's follow-up to the 2013 Marcia Gay Harden-Aidan Quinn comedy, "If I Were You."
"We could not have a better cast," Carr-Wiggen said in a statement announcing "If You See Her" this week. "Janet Montgomery and Sara Paxton are giving brilliant performances that are both hilarious and heartbreaking."
"When Heather and Sarah Ann were kids they knew they would be best friends forever," a synopsis said. "But Heather left the small town on the last day of high school vowing never to return. Forced to return when her father becomes ill, the cynical young documentary filmmaker is pressured into filming Sarah Ann's wedding video. Heather is convinced that the anarchist filmmaker and bubbly pink-wearing bride have nothing in common, but as the big day approaches she finds that no one is quite what they seem -- especially the old friend she thought she knew better than anyone."
