Mr McTiernan was originally accused of lying about hiring former celebrity private investigator Anthony Pellicano to wiretap film producer, Chuck Roven, after they both worked on the movie Rollerball.
Although Mr McTiernan is likely to be ordered to report to prison, his lawyer said there was still a motion before the judge to reduce or eliminate his sentence on the grounds there has never been any evidence presented that Mr Pellicano actually wiretapped Mr Roven.
