Since talent shows have long ceased to be about the talent, the focus, as "America's Got Talent" returns Tuesday (9 p.m., NBC10) is on the judges, with Heidi Klum and Mel. B. joining Howard Stern and Howie Mandel at the judges' table.
So, a German supermodel and a British pop star? That's a lot of accents for a show with "America" in the title, but by this time, we're used to having the whole world judge us -- Simon and the Supernanny taught us.
Feeling smarter than that? BBC America's Bang Goes the Theory" (not to be confused with the CBS sitcom of the similar name) premieres with three back-to-back episodes beginning at 9, with the first featuring a challenge involving homemade biofuels. (Did I mention cows were involved?)
