Fall TV Preview: Monday's Returning Shows

COSBY
We're in the process of reinventing the show,'' says new executive producer Tom Straw. ''Rather than farcical high jinks, we want more character-driven plots.'' Along those lines, there'll be less slapstick and more interaction between Bill Cosby's Hilton and his latchkey-kid neighbor, Jurnee (Eve's Bayou's Jurnee Smollett). Madeline Kahn's New Agey Pauline will be toned down, and Phylicia Rashad's long-suffering wife, Ruthie, will be tinkered with too. Says Straw, ''We don't want her always to have her hand on her hip, rolling her eyes at Hilton.'' We know the feeling.

SUDDENLY SUSAN
Susan (Brooke Shields) will finally start dating her editor, Jack (Judd Nelson), and Vicki (Kathy Griffin) is now married to a rabbi, Ben (Albie Selznick). But what America really wants to know is, What's up with Judd Nelson's hair? ''Jack's hair is always a barometer of his mental stability,'' explains exec producer Steven Peterman. ''For a while, he's going to be on good behavior, so he'll have nice hair. Once his hair starts acting up, you'll know that the relationship is in trouble.'' Too bad Shields can't use the same system with balding real-life hubby Andre Agassi.

MELROSE PLACE
Andrew Shue, Alyssa Milano, Linden Ashby, Brooke Langton, and Lisa Rinna have moved out, while Days of Our Lives' Steve Wilder, The Untouchables' John Haymes Newton, and General Hospital's Rena Sofer are checking in. Expect the show to focus on Heather Locklear's Amanda and feature less outlandish story lines, although executive producer Charles Pratt Jr. promises ''it's going to be steamier than ever. We have our usual sexual-obsession stories, which are relatable with the stuff you see on Jerry Springer about the lengths people will go to bed the objects of their desire.'' Josie Bissett's Jane has returned — and reunited with ex-hubby Michael (Thomas Calabro). ''Michael changes into this softie,'' says Bissett. ''It's really cute, because you're so used to him being such an a--hole.''
