Bits and pieces, odds and ends, stuff 'n' nonsense:

-REMEMBER HOW your mother always used to tell you to wear clean underwear in case you were in a car accident?You'd better wear clean underwear to San Jose, Calif., theaters, too.

The AMC Theater chain has refused to accept a San Jose laundromat's ad because it shows underwear in a hamper full of dirty clothes.

The image is the same as a billboard ad campaign for Oasis Laundries Inc., which has been posted in San Jose for the past three months. The same picture is on the billboards, a hamper overflowing with dirty clothes - including underwear - and the adline says, "Are you buying underwear to avoid your laundromat?"

Despite the fact that the ad has been seen by millions, AMC Theaters found it offensive and refused to show it in the chain's movie houses.

That's OK, of course. But there is an irony here.

The movies AMC shows are all the same first-run movies that run everywhere in the country, including R-rated films with nudity, violent gore and graphic sex.

AMC Theaters doesn't censor its movies, of course, but finds dirty underwear is offensive.

Go figure.

-WALT DISNEY CO. filed suit against the Academy Awards the day after this year's Oscar show for using Disney's patented Snow White image in the Oscars program's opening production number. (It was settled out of court a week later, by the way, with an apology from the academy.)

That's wild enough, but did you see what Disney spokesman Erwin Okun said about the suit?

"We sue all the time," he told the Associated Press.

Makes you wonder who else has been fooling around with Walt's legacy?

Who would have thought that Mickey, Donald, Goofy and friends were a bunch of ambulance-chasers?

-KIM BASINGER, as you may have read, has made a unique investment. She bought a small town in her native Georgia.

Basinger paid $20 million for Braselton, Ga. - commercial and private property totaling about 1,600 acres. Braselton is 40 miles northeast of Atlanta and has a population of about 500. Exempted from the sale were private homes not owned by the Braselton family and property owned by the town government.

Basinger's most recent film was "My Stepmother Is an Alien," and she has a prominent role in the upcoming "Batman."

She didn't say whether "Braselton" will be renamed "Basinger," but it makes you wonder if other movie stars might not be motivated to buy small towns and re-name them after themselves.

Can you picture Schwarzenegger, N.D.? Or Streisand, Calif.? Or perhaps DeVito, Mass.

Maybe Orem will become Redford, Utah.

-ROGER RABBIT RETURNS this summer in a cartoon short mounted by the same Disney animators who did last year's hit film "Who Framed Roger Rabbit," which introduced Roger and Baby Herman and other new cartoon characters to the world.

The new short, titled "Tummy Trouble," will use the "Maroon Cartoon" logo from the film, which was a spoof of the Warner Bros.' "Looney Tunes"/"Merry Melodies" logo. The cartoon will be attached to the front of a Disney family feature titled "Honey, I've Shrunk the Kids," a fantasy-comedy about psychiatrist Rick Moranis accidentally shrinking his children to thimble-size.

The premise has Roger Rabbit baby-sitting Baby Herman when the precocious child swallows a rattle. Needless to say, Roger's means of trying to retrieve the toy are less than conventional.

-"BACK TO THE FUTURE II" has had its release date pushed back to Christmas of '89, to avoid the summer sequel glut.

But more interesting is that "Back to the Future II" is being filmed back-to-back with "Back to the Future III," which will come out in the summer of '90.

Why film them both now? Partly so director Robert Zemeckis, who also did the original "Back to the Future" and recently helmed "Who Framed Roger Rabbit," won't have trouble pulling his cast together again - Michael J. Fox, Christopher Lloyd, Lea Thompson, Crispin Glover, etc. They are all busy folks these days.

Another reason is so Fox will not get much older - or older-looking - before they get around to the second sequel.

This isn't the first time this has been done, of course. In the mid-'70s Richard Lester shot "The Three Musketeers" and "The Four Musketeers" in tandem, but he led his cast to believe it was for one long film. (Cast members, led by Charlton Heston, later sued for salaries from the second film.)

The makers of the "Allan Quatermain" films with Richard Chamberlain also shot two movies at once - and they looked like rush jobs.

But "Back to the Future II and III," of course, are going to be much more high quality pictures.

We hope.
