Only at TCA

Revelation of the Day: Mark-Paul Gosselaar, whose next attempt to make people forget him as  Zach on Saved by the Bell is called Raising the Bar (TNT, Sept 1), told TCA critics today that he had to regularly dye his hair blonde to play Zach. He also wore clothes as Zach that weren’t his, they were costumes. Imagine.  “That wasn’t Mark-Paul in school, I was  playing a character,” he said. But my mother, she told me…

Next Revelation (or a sign that the Apocalypse is upon us): Fox Reality Channel President David Lyle says 32 reality shows will be introduced on broadcast television this year. There will be 140 introduced on cable.

Unimportant But Nice Revelation: Ewan McGregor, here to pitch Long Way Down, where he and a mate take their bikes from Scotland to Namibia (Fox Reality Channel, 9pm, Aug 2), has to be one of the most articulate actors around. The “bloke on a bike” spoke about everything from being anonymous in Africa to the good Samaritans who transport AIDS HIV anti-viral medicines to patients in Africa, where transportation is sometimes a luxury. (Part of McGregor’s reason for the trip was to publicize Africa’s plight and the need for westerners to support charities.) There’s no way to know if Long Way Down will find an audience on FRC, but it sounds like McGregor had quite a journey.
