HIS HOMETOWN Bruce Springsteen will perform two informal shows in his hometown of Asbury Park, N.J., on Thursday and Friday to warm up for his European tour, which begins April 9 in Barcelona.

IDLE CHATTER The New York Post reported yesterday that Heather Locklear, out of a job since the cancellation of ''Melrose Place,'' might be drafted by Aaron Spelling to help rejuvenate ''Beverly Hills, 90210'' at a paycheck of $250,000 per episode. A Fox representative said ''at this point it's total rumor.''
CASTING Kevin Bacon's motivation for joining ''The Hollow Man'' is so transparent: He'll play a scientist who discovers a way to turn himself invisible, and this power spurs his dark side. Paul Verhoeven (''Starship Troopers'') will direct.... Morgan Freeman will star in ''Chief,'' a comedy based on the true story of an African tribal chief's son who has to return to his father's side after becoming acclimated to the modern world during an extended stay in America.

REEL DEALS Two entries in last year's horror boom have inspired follow-ups: ''Urban Legend'''s middling $38 million gross was enough to inspire the producers to begin developing a sequel. And Universal has a fifth ''Child's Play'' movie in the works. Jennifer Tilly may reprise her role from ''Bride of Chucky.'' The writer of all four previous installments, Don Mancini, will script again, and this time he'll also direct. Director Tom Shadyac (''Patch Adams'') has bought the script ''Karaoke Knight'' to produce, with an eye for Ben Stiller to star. The antic comedy centers around a karaoke wannabe with all charisma and no voice.... Michael Cimino (''The Deer Hunter''), who permanently lost his wunderkind status after 1980's expensive bomb ''Heaven's Gate,'' will take another stab at directorial fame with ''1500.'' The movie centers around Portugal's discovery of Brazil in the titular year.

LAWSUIT Two former business associates of Muhammad Ali are suing Sony to stop Columbia from making a biopic (being developed for Will Smith) about the boxer's life. They claim they have the rights to Ali's story. Ali's former manager, Jabir Herbert Muhammad, and Jason Marcus Hirschfield, the son of his ex-attorney, say that they had previously formed Muhammad Ali Productions with the former heavyweight champ for the sole purpose of selling his life story, and were talking to other producers before learning Ali had already sold his tale and had shut them out. They are asking for $50 million in damages. Ali's wife, Lonnie, said the suit was a ''calculated attack on Muhammad personally.''
