Donal Logue joins the cast of the NBC drama series “Life” this fall. He plays the character of Capt. Kevin Tidwell. My guess is that many of you know Donal than may know “Life.” He starred in a traditional sitcom on Fox, “Grounded For Life” and a non-traditional sitcom, “The Knights of Prosperity,” on ABC. My guess is that NBC is counting on Donal to add a new dimension of familiarity to “Life,” which built a rabid, if small, fan base in its first season and hopes to improve upon it this year. It airs Wednesdays at 9 p.m. Donal Logue • •
