I watched JAG tonight and they had a memorial tribute to Trevor Goddard (Mic Brumby). I didn't even know he died...unless you count the Hoover Floor Mate commercial.
Turns out Trevor died of heroin, cocaine, vicodin and valium overdose and the death ruled accidental. His father revealed at the funeral that Trevor was not Australian, as he had claimed but actually from England. He made up the story to get work in Hollywood.
Looks like he lived out his life in true Hollywood form, including the ending.
