Jenna Elfman has joined the cast of DirecTv's acclaimed drama Damages for its fifth and final season.

The comedic actress will take on the more dramatic role of an investment bank employee who finds herself at odds with her company's conduct. She will be joined by recent cast addition Ryan Phillippe, whose character stars as the founder of a website intent on exposing corporate and governemnet transparency.

Together, they will lay the groundwork leading up to the case that will pit series stars Glenn Close and Rose Byrne, as Patty Hewes and Ellen Parsons respectively, against each other.

Damages will return to DirecTv in 2012 for its climactic Season 5 run.
