Can you spell overexposed? Tom Bergeron is verging on becoming the one-and-only face of ABC. The host of “America’s Funniest Home Videos” and “Dancing with the Stars” will helm the prime-time broadcast of the 2008 Scripps National Spelling Bee (7 p.m., ABC).

Earlier portions of the competition will be broadcast on ESPN (10 a.m.). Chris McKendry (“SportsCenter”) will host the early rounds. Held in Washington, D.C., every year, the Scripps bee attracts more than 280 championship spellers, ages 8 to 15, who have qualified for the trip to our nation’s capital by winning locally sponsored rounds in their home communities.

¢ Scheduled on a two-hour “Dateline” (8 p.m., NBC), Chris Hansen confronts six women who have been caught on tape discussing arrangements with people they believed were hitmen. Now that’s a whole new twist on the predator-caught-in-the-kitchen narrative. A second segment investigates a wife’s shaky alibi in connection to the disappearance of her husband, a talented airline mechanic.

¢ A jealous TV star (Brittany Murphy) uses her boyfriend’s (Ron Livingston) digital organizer to learn more about his past flings in the 2004 romantic comedy “Little Black Book” (7 p.m., Fox). Gee, somehow this one passed me by. Reviewers were harsh. Rolling Stone called it “a comedy of punishing tedium.” The Wall Street Journal used the word “tiresome.” The online reviewer for Salon.com thought, “The movie can’t distinguish between what’s likable and human and funny and what’s simply repellent.” Yikes.

¢ “Man vs. Wild” (8 p.m., Discovery) becomes man vs. cold as host Bear Grylls drops in on the Siberian tundra, a frosty and forbidding locale where temperatures can dive to minus 30 Fahrenheit.

Cult choice

Oscar-winner Halle Berry received some of the harshest criticism of her career for her turn in the 2004 fantasy “Catwoman” (6 p.m., Oxygen), a comic-book fiasco best thought of as so bad it’s worth seeing once.
