Tom Hanks, his wife Rita Wilson and Nia Vardalos, the star of their hit My Big Fat Greek Wedding production, are set to go to trial to fight for money they claim they're owed. The trio co-produced the 2002 movie and maintain their co-financiers at Gold Circle Films still owe them a share of the profits. The ongoing lawsuit was referred to mediation on Monday and Los Angeles County Superior Court Judge Yvette Palazuelos set a court date for January 20 just in case the trio's mediation battle fails.
