It’s magic week, boys and girls! ABC will lead things off May 8 with a live special starring David Blaine. Using a life support system, he’ll spend a week in a spherical aquarium, then conclude by trying to surpass the record for holding one’s breath underwater, 8 min., 58 sec. I assume no goldfish will be at risk. Keith Barry’s May 12 special is a lighter affair. Teamed with stars including Elijah Wood and Matthew McConaughey, he plays elaborate card tricks and games that create an illusion of mind reading. He’s ingenious, but the rapid-fire bluffing he uses to rope people in wears thin. He’s like a spell-casting telemarketer.
