A new gangland biopic about mob boss John Gotti includes scenes of a triumphant Dapper Don leaving a Brooklyn courthouse after his acquittal — but the real-life drama unfolded a bit differently.

John Travolta, portraying the godfather, will be shown defiantly strutting from the courthouse with his real wife, Kelly Preston, who portrays Gotti’s wife, Victoria.

In fact, after his trial in March 1987, Gotti snuck out a side door at Brooklyn federal court and was whisked away by one of his associates.

“The Life and Death of John Gotti” also features the infamous hit on Gambino crime boss “Big Paul” Castellano at Sparks Steak House in Midtown.

But the mob assassination, immortalized on the cover of The New York Post, was re-enacted for the film in Cincinnati instead of the gritty streets of Gotham.

The 1985 shooting left Castellano’s lifeless body in the gutter and signaled the rise of the Teflon Don as the most powerful mob boss in the city.

Gotti waited in a nearby car with several associates as Castellano was gunned down.
