This is so not the Maya Rudolph version. Gina Gershon plays uberdiva fashionista Donatella Versace in Lifetime's House of Versace (Saturday, Oct. 5, 8/7c), a bio-flick packed with high fashion and epic tragedy. The film kicks off in 1996 in Milan with Donatella serving as creative muse to her brother, superstar designer Gianni Versace (Enrico Colantoni). When Gianni is slain by a serial killer, Donatella is forced to take his place as head couturier to keep the company afloat. All that grief and pressure soon has her strung out on booze and cocaine, and profits slide 60 percent. Cue the family intervention and a forced stint in rehab. TV Guide Magazine spoke with Gershon about the challenge of playing Donatella minus the Saturday Night Live shtick.
