rumored talk show is going to happen on ABC. How long it will happen is anybody's guess.
As several have noted, Alec has a rather abrasive personality. With its confining gameplay, Match Game has kept his worst impulses under control. A freewheeling talk show might let the inner Baldwin beast loose. Or conversely, he might try to keep things so controlled that the talker could turn bland and tedious.
If you vaguely remember that Alec flopped once before with a TV yakfest, you're right. MSNBC tried him for fifteen minutes of not-so-fame. The numbers tanked in a hurry, even with the politically congenial (for Baldwin) MSNBC audience. We'll see how he does with the much less skewed ABC viewership.
At least he'll get a pretty good lead-in for his show's initial "sneak peek." Sundays with Alec Baldwin follows the Oscars on March 4. Though the Oscars have been losing viewers lately, too.
