The Last Five Years at New Mexico Actor's Lab

The Last Five Years is a musical written by Jason Robert Brown, with a cast of two. The story explores a five-year relationship between Jamie Wellerstein, a rising novelist, and Cathy Hiatt, a struggling actress. The show uses a form of storytelling in which Jamie's story is told in chronological order (starting just after the couple have first met) and Cathy's story is told in reverse chronological order (beginning the show at the end of the marriage). The characters do not directly interact except for a wedding song in the middle as their timelines intersect.

It premiered at Chicago's Northlight Theatre in 2001 and was then produced Off-Broadway in March 2002. Since then it has had numerous productions, both in the United States and internationally, and a Broadway production in 2025. A movie version appeared in 2014.
