Smith's double-decker luxury trailer was plonked down in the middle of a tiny street in Soho while the actor shot "Men in Black III" -- but after several residents complained it was blocking traffic, giving off fumes, and screwing up local businesses ... the studio towed it to a nearby parking lot.
And to give you an idea of how absurd this thing is -- the 53-foot trailer also boasts marble floors, a massive 100-inch TV, a bedroom, and several offices.
