All those years ago
Business has gone downhill for both director M. Night Shyamalan and Mel Gibson since they teamed up for 2002's "Signs" (7 p.m., AMC), an engaging thriller, as long as you ignore the ludicrous ending. Joaquin Phoenix, Cherry Jones and Abigail Breslin co-star.
Soul singer
I consider myself something of a music buff, but it turns out one of the most influential artists in American music was a mystery to me. "Sister Rosetta Tharpe: The Godmother of Rock & Roll" (9 p.m., TPT, Ch. 2) examines how this gospel singer inspired Elvis Presley, Jerry Lee Lewis and Johnny Cash.

Chelsea Handler once again taps one of her famous friends for the post-show parody, "After Lately" (9:30 p.m., E!). This time around, it's Oscar winner Reese Witherspoon, who plays along as Handler tries to pass herself off as her generation's answer to Larry Sanders.
