TV picks for Nov. 2-3: 'Thundermans,' 'Black Girls Rock,' 'Secrets of Selfridge'

If you think Hannah Montana had it tough maintaining a secret identity, wait until you meet "The Thundermans" (8 p.m. Saturday, Nick), teenage twins who can't let their schoolmates know that they're superheroes. A leak would make it super awkward when picking sides for dodge ball.

Queen Latifah, Kelly Rowland and Venus Williams are among the big names who think "Black Girls Rock! 2013" (6 p.m. Sunday, BET), as opposed to 2009, when black girls merely swayed back and forth.

While waiting for new episodes of Jeremy Piven's "Mr. Selfridge," check out "Secrets of Selfridge" (7 p.m. Sunday, TPT, Ch. 2), a documentary on the legendary shopkeeper who believed "the customer is always right." Unless he wants to eat nothing but sushi. Then, not so much.
