This is a stoner film written and directed by Thomas Haden Church. If I have seen it, I don’t remember it at all.
One evening the Murphy brothers inadvertently discover something quite amazing: The Map. They are shocked to find that their long lost parents, the Hippies Murphy, have bequeathed to them a map to a mythical field of pot.
There is a very amusing review on efilmcritic.com:
The characters are magic. The dialogue, twisted and insane and perfect. The timing, fabulous. But then the storyline kicks in and, sadly, everything goes to hell. Well, maybe not hell… but a place very warm. And red. And Satan is there. Okay, it’s hell.
It seemed that Mia was topless in about a zillion grade-B films and videos from 1999-2003, but then basically disappeared when she and Thomas Haden Church became a couple and had children. IMDb indicates that she was in a film last year – her first credit in 15 years.

Good score on his part.
She did a porn and participated in hardcore scenes in “Sex Files 1” by XPlor media in 1997. It was only on VHS. It is a difficult title to find because of the generic name, and I have never been able to locate it except one Roger T. Pipe review and small pictures of the front and back cover.
Thomas Haden Church was married to her? Alright! She is fine. Definitely made late nights a fun to watch in the early 2000s. Softcore cinema in the 80s, 90s, and early 2000s was a golden age. It got dumb ever since and it’s all but kind of disappeared.
They never married, but were together for several years.
