American Pie Presents: The Book of Love

Beethoven's Christmas Adventure
What they share
Both films are directed by John Putch, and they both carry the playful mood tag, and they sit in Comedy territory. If that's the register that drew you to American Pie Presents: The Book of Love, the second film will land in a comparable space — through a different lens.
