JASON RITTER

The Class (CBS)
Jason Ritter, 26, has big comedic shoes to fill following in the footsteps of his late father John Ritter. "Right before I went on (an audition), someone would go, 'Oh, we all loved your dad,'" he told the Newark Star-Ledger. "My insecurities would overwhelm me." Now, though, Ritter – who's an uptight guy arranging a reunion on Class – is fiercely confronting comparisons. "I really feel like I am putting my head into the lion's jaws."
