"Showgirls" star Glenn Plummer got slapped with a lawsuit from a guy who should know a lot about courtroom action ... because his name is Lawyer Henderson

According to a lawsuit filed in Georgia last week, Plummer screwed over Lawyer when, at the last minute, he dropped out of a movie Lawyer was making called "The Governor's Daughters." 

Lawyer alleges he paid Plummer for his role, shelled out travel expenses, and suffered damages to the tune of $50,000. Not shockingly ... Lawyer is representing himself in the lawsuit. 

Calls to Plummer's rep were not returned.
