When the Sky Falls is a 2000 film à clef directed by John Mackenzie and starring Joan Allen. The narrative centres on reporter Veronica Guerin, who wrote about drug-related crime for the Sunday Independent, and her eventual murder.

The film received negative reviews, with criticism towards its directing, writing, script, and renaming of the characters, though Allen's performance was better received. Its lack of a better connection to Guerin's story was also widely panned. Another film based on the same story, entitled Veronica Guerin, was released in 2003, to far stronger reviews and had Cate Blanchett in the title role.
