A look inside Hollywood and the movies. : SEQUEL CITY : Honey, I Blew Up ‘Home Alone’

It seems that the “Honey, I . . .” movies are fast becoming a series. No sooner has “Honey, I Blew Up the Kid” opened than a third installment is in the works from the Walt Disney Co.

After shrinking the Szalinski kids in the first film and blowing up baby in the current one, sources say the latest twist will be to shrink the parents--who’ll then watch in (mock) horror as their kids get the run of the house.

The studio is anticipating that the successful PG-rated formula has long-running comedic--and commercial--possibilities.

In the first “Honey, I Shrunk the Kids,” Rick Moranis played the nerdy inventor who accidentally zapped his kids into microscopic size, swept them up and took them out to the trash. They then had to make their way back through the back-yard thicket of gigantic insects and a torrential lawn sprinkler downpour only to end up just a mouthful away from being swallowed along with a spoonful of Cheerios. The modestly budgeted movie was a sleeper hit in 1989, grossing $130.7 million in the United States and Canada.

“Honey, I Blew Up the Kid” has the newest Szalinski offspring, baby Adam, zapped by Dad, but this time, the experiment results in the toddler growing to King Kong proportions and threatening the peace of downtown Las Vegas. Much of its reported $40-million budget went into the expensive, technically exacting blue-screen process necessary for juxtaposing giant baby against normal-sized folk.

Disney executives toyed with various titles, including “Honey, I Blew Up the Baby,” a line that’s right out of the movie, but between the so-called marketeers and test audiences determined that the imagery that conjured up was “just too close to seeing the baby go ka-boom--blown to bits.”

No word yet what’s being thought up for the parents-as-specks scenario. “Honey, They Don’t Miss Us?” maybe?
