she plays his wife in this https://pbs.twimg.com/media/E2zLwzhXwAYW8lk?format=jpg
I just watched this, and it was never clear to me at all she was his wife. I just thought she was the bartender at his club.
i had skipped through the movie a bit and couldn't even find her
Every scene that takes place at the bar/club where Mel Gibson hangs out, she's there.
