Regardless, her performance was a smash hit, which led to the producers asking her to return for another appearance. Reese turned down the offer.

Although Reese was excited to play the country legend, she was mortified once she heard a recording of herself singing. The actress went on to call her attorney four times in a row to get out of the project.

Ultimately, Reese stayed attached to the film and, over the course of six months, received two hour-a-day voice lessons.

Political Praise

Fun fact: Reese's film Election is Barack Obama's favorite political movie.

Director Alexander Payne revealed that the former President of the United States told him that the 1999 comedy was his favorite political film.
