Scowling Will Smith reduced to using regular trailer

Will Smith’s cosmic-size ego has come crashing back to Earth.

The “Men in Black” star spent yesterday primping and lounging in a bland, generic movie trailer on his film’s SoHo set, a day after he was shamed out of his gargantuan, marble-floored mobile mansion by angry locals and Mayor Bloomberg.

“Will has to live like normal people — at least for today,” a set source told The Post.

“It’s like going from a BMW to a Toyota,” another production source said.

Smith spent the shoot in the kind of plain-white trailer from Haddad’s that seems to grace every movie set in the city, with run-of-the-mill furniture and — gasp! — no cable.

Meanwhile, just out of reach was his specially made, $2 million, 53-foot double-decker trailer. It sat empty in a parking lot about half a mile away, a similar distance from his $25,000-a-month Bond Street apartment.

When confronted by The Post about his new on-location digs, Smith scowled and stalked away.

He sang a different tune on Wednesday, when he literally held his belly and issued a hearty guffaw when asked about his street-blocking, exhaust-spewing ride — which drew complaints from neighbors and business owners and the ire of Mayor Bloomberg.

His no-frills Haddad’s T7716 — which no other actors could access — was a far cry from his previous ride, dubbed “The Heat.”

Marketed by its manufacturer as a “mobile estate,” “The Heat” towered two stories over Broome Street and was joined by an equally huge gym trailer around the corner. It featured a spiral stair case, granite counters, a lounge and a personal film- screening room.

The new Haddad’s ride is a 35-foot-long shanty that, at two points, extends out horizontally by about five feet. It’s barely as high as a fire escape.

The “I am Legend” star had access only to a small bedroom, a bathroom, a table and an area for his wardrobe and makeup.

Still, he didn’t skimp on security.

Smith’s 7-foot-tall personal bodyguard was stationed outside to keep the media and even some of the film’s crew at arm’s length.

Smith co-star Josh Brolin and “Men in Black 3” director Barry Sonnenfeld were issued similarly Spartan accommodations when filming began in New York this week.

Smith was also separated from his mobile gym, a 55-foot trailer that was moved to the parking lot and parked next to “The Heat.”

After The Post broke the story, the Mayor’s Office of Film, Theater and Broadcasting asked the production to remove the trailer — leased to Smith for $9,000 a week.

Attendants at the Park Fast at Dominick and Hudson streets declined to say how much it cost to dock the exiled trailer and gym.

“But everybody pays,” one deadpanned.

Two city lawmakers have proposed legislation to limit the size of film-production vehicles.
