"Love, ___" (2014 rom-com starring Lily Collins)

ROSIE

This film adaptation of Cecelia Ahern’s novel follows a lifelong friendship turned romance between two childhood pen pals from Ireland and America. The title character shares her name with a classic WWII-era symbol.

This clue references the 2014 romantic comedy Love, Rosie, where Lily Collins plays the lead role of Rosie Dunne. The comma in the title hints that the answer is a name, and since the movie’s full title is Love, Rosie, the blank simply fills in "Rosie." It’s a straightforward fill-in-the-blank based on the film’s well-known title.
