The song Oscar Isaac sings was originally supposed to be written by someone else for him to perform, but being a student from Julliard, he told producers he could write a song himself. The song, "Never Had" was Oscar's creation.
The song "Never Had," sung by Oscar Isaac in the bar is a slightly different version than what appears on the movie soundtrack. In the movie, the last line of the second verse says, "And I hope this song I'm singing Someday finds you Wherever you may be." The soundtrack version says, "And I hope this song I'm singing Someday finds you My letter to Elise."
Scott Porter's character is also named Scott Porter. When he is serving behind the bar you can hear people call him Porter.
Channing Tatum and Jenna Dewan (Jess) were married in real life two years before the film.
