EVEN ODDER COUPLE?
Oscar and Felix may be bickering again soon. Jack Lemmon, Walter Matthau, author Neil Simon and producer Howard W. Koch had lunch together recently at the Beverly Hills Tennis Club, partly to discuss how best to pool their creative resources to do a movie sequel to The Odd Couple. The original 1968 film, using Simon's screenplay and based on his Broadway play, starred Lemmon and Matthau and was produced by Koch. Lemmon later said the subject of the lunch meeting was "more wide-ranging" than just The Odd Couple. "We definitely want to work together," he said. "When we're free of our individual commitments, maybe we can."

AVA, THE BOOK

When a star the magnitude of Ava Gardner dies (see page 72), inevitably there is a rush to learn everything about her and her impressions of other equally famous people. Bantam Books is said to be planning an authorized book on Ava, but she had also revealed a great deal to author Lawrence Grobel. He first interviewed the late star in her London apartment in 1986 while researching his 1989 book on director John Huston and the Huston clan, The Hustons. (Gardner starred in three John Huston movies.) Grobel says he spent another six weeks with her when she visited Los Angeles in early 1988, recording further conversations for a book she wanted him to write about her. Although the deal between them was never signed, Grobel kept the tapes and his notes. Now that she has died, he is again considering a book.

In addition to discussing her many romances, Grobel says, Ava also shared her feelings about some of her co-stars. Of Paul Newman, with whom she starred in 1972's The Life and Times of Judge Roy Bean, Grobel says she said, "I can't stand that man. He's one of my unfavorite actors. He's an egomaniac, and so false. He's 'on' all the time." When Grobel asked her to name other actors she disliked, the two she mentioned were Kirk Douglas and John Wayne.

PRE-NUP NIPPED
Roseanne Barr, of ABC's hit sitcom Roseanne, stands by her man. Not long before her marriage last month to comedy writer Tom Arnold, Barr was advised by both her attorney and business manager to sign a prenuptial agreement with Arnold. (Arnold spent part of December in a drug-and-alcohol rehabilitation center.) Barr not only didn't take their advice, she fired them and her public relations firm, PMK. Not that anyone's saying there's a connection. The attorney, Barry Hirsch, and business manager, Marshall Gelfand, both refused to comment, as did Barr's manager, Arlyne Rothberg.

BROADWAY BUCKAROO

It sounds like Keith (Cold Feet) Carradine is headed for Broadway to play cowboy comedian Will Rogers in a new musical, Ziegfeld Presents Will Rogers. The show was originally developed for singer John Denver. Carradine, of course, proved he could sing back in 1975's Nashville with his semihit, "I'm Easy."

Cy (City of Angels) Coleman is writing the music, and Betty Comden and Adolph Green are the lyricists. The book is by Peter Stone. Rehearsals begin in June, and the opening is set for October, says producer Pierre Cossette.

DOGGING IT
Surely you have heard of celebrity calendars. But a calendar filled with dogs of the stars? The Ralston Purina pet food company has a 1991 version coming out ($8.95 plus proof of purchase), having talked Bob Hope, Michael Keaton, Frank and Kathie Lee Gifford, Barbara Mandrell, Kirstie Alley and other celebs into letting their dogs smile for the camera. And, no, the stars will not appear with their dogs.
