Christmas is upon us ” at least on television. A full 12 days before Thanksgiving, the Hallmark Channel unspools “Christmas with Tony Bennett: Behind the Scenes” (7 p.m. today), the first holiday special of the year. As the title implies, the show is really a documentary about the making of a new CD, Bennett’s first Christmas album since 1968.

• Kelsey Grammer is never afraid to play the fool ” as long as the fool gets to wear designer clothes, sip expensive wines and hobnob with the posh set. Grammer does not stray far from his “Frasier” form in the genial, if confused, holiday movie “Mr. St. Nick” on “The Wonderful World of Disney” (6 p.m. Sunday, ABC).

Grammer plays Crown Prince Nick St. Nicholas, the son and heir to Santa Claus (Charles Durning). He’s due to inherit the family business and extensive Christmas Eve obligations, but he’d rather hang out in Miami Beach soaking up the sun and ogling bikini-clad girls.

Nick falls for a scheming TV meteorologist (Elaine Hendrix) who bamboozles him into participating in a dot-com fraud. Nick also hires a feisty Latina chef (Ana Ortiz), who seems to see through his weathergirl’s fraudulent plans.

With so much going on, “Mr. St. Nick” may be the most convoluted and far-fetched Christmas movie since “Santa Claus Conquers the Martians.”

• “Inside TV Land: Taboo TV” (8 p.m. Sunday, TV Land) looks at how television has evolved, or devolved, since the squeaky-clean households of “Father’s Knows Best.” In television’s infancy, advertisers demanded that programs adhere to a strict code of decency.

While early television characters refrained from sex and profanity, they smoked like fiends and frequently got tipsy. “Taboo” includes vintage clips from “The Dick Van Dyke Show,” in which Rob and Laura praise the virtues of Kent cigarettes. On “Bewitched,” Larry Tate’s wife fortifies herself with martinis before telling her husband that she is expecting his baby.

• A talented broom-flier (Daniel Radcliffe) is educated to fulfill his enchanted destiny in the 2001 fantasy “Harry Potter and the Sorcerer’s Stone” (7 p.m. today, HBO). Scrupulously faithful to J.K. Rowling’s best-selling tome, and belabored by expensive and indulgent special effects, “Potter” unfolds at a maddeningly sluggish pace. It has a two-and-a-half-hour running time, but it seems much longer.
