NBC has confirmed that Jack Black and Jessica Alba will both appear in the hourlong, post-Super Bowl episode, which is titled "Stress Relief."

According to the network, Black and Alba play characters in a bootlegged movie that the Dunder Mifflin staffers watch during the work day. The network has hinted that there might be other Hollywood stars who cameo in said film; we'll keep an eye out. Super Bowl XLIII airs on NBC on Sunday, Feb. 1.
