The Answer Man
(2009)

Arlen and Elizabeth fall in love. Kris and Anne meet and fall in love. Arlen continues to be a rat. Elizabeth finally calls him on the rug and walks out.

Last scene surprises us: Arlen does a book signing in Kris' store which brings both Arlen and the store back to life.

Arlen and Elizabeth make up on the sidewalk.

Thanks Mary M!
