In early January 2007, production on the film "I Know Who Killed Me" was put on hold when Lohan underwent appendix surgery. While Lohan was in rehab, she continued shooting the film, returning to the facility at night. Shortly thereafter, Lohan withdrew from a film adaptation of Oscar Wilde's "A Woman of No Importance", her publicist stating that Lohan needed to "focus on getting better." Lohan was replaced in "The Edge of Love" in April 2007, shortly before filming was to begin, with the director citing "insurance reasons" and Lohan later explaining that she "was going through a really bad time then."
