Trial in a lawsuit alleging that entertainment website IMDb.com Inc. illegally publicized an actress’s real age, causing her to lose prospective casting roles, has been postponed because the plaintiff’s lead counsel, John Dozier, an expert on Internet law, died on Aug. 6.

Huong Hoang, a Texas actress who goes by the stage name Junie Hoang, had retained Dozier of Dozier Internet Law in Richmond, Va., to sue IMDb.com and its parent company, Amazon.com Inc., for publicizing her age online after gleaning the information through a credit card number she provided while signing up for the website’s professional network.
