MOVIES In a sign that Hollywood may finally be running out of human superheroes, Underdog is now getting the live-action movie treatment from Walt Disney Pictures and Spyglass Entertainment. (Yes, with a real dog, plus some CGI.) No firm casting ideas yet, but Spyglass cochair Roger Birnbaum says, ”I don’t think you’re going to see a French poodle or dachshund in there.” Casting agents, take note. . . .Jennifer Garner will star in and produce a remake of the Japanese supernatural romance Be With You, about a dying young woman’s promise to return to her husband and son — and her family’s encounters with an eerie look-alike a year after her death. . . .The biopic business keeps booming: The folks who brought us Ray are gearing up to tackle the late, great Rodney Dangerfield. It will be based in part on Mr. No Respect’s autobiography, It’s Not Easy Bein’ Me, but producer Howard Baldwin is really interested in his less funny years: ”It’s about a guy who, in the prime of his life, dropped out of the comedic world and sold aluminum siding for 12 years. I want to learn about that.”. . .Now that Christina Ricci has signed on as a sex addict in Black Snake Moan, who else is writer-director Craig Brewer courting for his follow-up to the Sundance fave Hustle & Flow? Samuel L. Jackson, as an ex-blues musician who becomes a father figure to Ricci, and Justin Timberlake as her long-suffering boyfriend. ”Justin and I are Memphis boys, and we’ve always wanted to work together,” Brewer says. ”I think he’s going to surprise a lot of people with this role.”

TELEVISION Alan Cumming will do a six-episode L Word stint when Showtime’s sapphic hit returns for its third season next year. He’ll play a promiscuous party promoter hired by Kit (Pam Grier) to manage her club. ”I sort of based him on people I know,” he says. ”All my partying is finally going to pay off — it wasn’t just hedonism.”
