CABLE truly is different than broadcast TV. HBO is developing a series with Red Hot Chili Peppers frontman Anthony Kiedis “based on his unconventional, rock ‘n’ roll childhood,” Variety reports. But blogger Ron Mwangagu hunga points out that Kiedis’ 2004 memoir, “Scar Tissue,” “has a disturbing amount of bragging about sex with underage girls. One of the girls, he confesses, grotesquely, was a 14-year-old dolled-up like Marilyn Monroe . . . another was a 15-year-old, Ione Skye . . . has the statute of limitations for statutory rape expired?” An HBO spokesman said, “We did not buy the rights to his book, and we are not dramatizing the book. This project is focused on Anthony’s life as an adolescent. The title, now tentatively called ‘Scar Tissue,’ does not refer to the book, but to the song.” The HBO show will focus on Kiedis and his father, “who sold drugs and mingled with rock stars on the Sunset Strip,” Variety reports.
