+ Will & Grace‘s Eric McCormack will return to TV as Mason, a newly promoted ad exec, in the TNT pilot Truth in Advertising. ”Mason is a nice guy in a cutthroat world,” says McCormack. ”If Mad Men is about the beginning of advertising’s golden age, this is about the end of it.”

+ South Park creators Trey Parker and Matt Stone are bringing the Canadian series Kenny vs. Spenny — which pits comedians Kenny Hotz and Spencer Rice against each other in silly, often humiliating challenges — to Comedy Central. ”We are fans,” says Stone, who’ll exec produce 10 new episodes with Parker. ”It’s one of those shows that hasn’t had its chance on American TV.”

+ Jenna Elfman has joined the cast of the Tim Allen comedy The Six Wives of Henry Lefay. Her character, Ophelia, is ”a diva, to put it mildly,” says Elfman, who was also just cast in the ABC comedy pilot Literary Superstar. ”Ophelia is liberating because I can just let it rip with her.”
