Bruce Beresford-Redman appeared in court in Cancun, Mexico, on Thursday for the first time to face murder charges in the death of his wife. He did not enter a plea.
Attorney Jaime Cancino Leon said he had found inconsistencies in the prosecution's case, but did not elaborate. He plans to ask for an additional three days to present his case for dismissal.
After that, the judge must throw out the charges or order a trial.
The producer spoke briefly at the preliminary hearing and complained he didn't have a consular representative when investigators questioned him after the April 2010 murder at a Cancun resort.
Beresford-Redman was charged in the state of Quintana Roo with aggravated homicide. The couple had been vacationing in Cancun on a trip to work on their troubled marriage, according to her family.
Monica Beresford-Redman's body was found nude and beaten at the resort three days after Bruce Beresford-Redman reported her missing. He has denied killing his wife.
