According to wiki, she retired from acting, had three kids, and opened her own acting school in Canada.
Jake, from Sixteen Candles.
But he isn’t missing, as the documentary proved.
Michele Miscavige, the wife of the current head of the Church of Scientology, hasn’t been seen in public since 2007.
He’s decomposing.
I was going to nominate A.J. Langer. She played Rayanne on My So Called Life. I read, years ago, that she married some European aristocrat and left Hollywood behind. Then I IMBd’d her and it turns out she’s been working all along. Just nothing I was aware of.
I’ve been in lust with AJ Langer since “Drexel’s Class,” which also included a young Brittany Murphy.
Steve McPeak
He was a daredevil back in the 1970s, and held many Guinness records for tightrope walking, bicycling, etc. At one point I believed he owned the longest vehicle in the world (an arctic vehicle with many large wheels).
Not sure what happened to him. I couldn’t find much via a google search.
Interesting addition to the list. I remember reading the GBWR and rolling my eyes every time I hit another McPeak record.
I guess he didn’t have much of a life other than that, so profuse listing in the Book is his whole biography. I suspect a lot of those records got purged with the other ephemeral, nonsense ones.
ETA: He’d be about 71 now. Not surprised he’s no longer in the public eye, if all he had was his fitness-based exploits.
ETA2: He seems to be living in Pagosa Springs, CO. He’s in various white pages listings.
Bolding mine. That’s a bit of an understatement.
He died in the 90s sometime. (And not from battling an immortal Egyptian soul-sucking demon, either.)
She’s actually English nobility now:
[QUOTE=Wikipedia]
Langer married attorney Charles Courtenay, Lord Courtenay, the son of the Hugh Courtenay, 18th Earl of Devon, in a civil ceremony in 2004. A formal wedding took place on April 30, 2005, in Los Angeles, California.[2] In January 2014, Langer and Courtenay permanently relocated their family to London. Upon the death of the current Earl, Langer (who holds the courtesy title “Lady Courtenay”) will assume the title of Countess of Devon, and will relocate to the family seat at Powderham Castle.

On another note, I saw a scene in a compilation porn video I rented in 1995, where I would swear the actress was A.J. Langer (who would have been 21 years old in '95). I mean, I know it was unlikely (and Internet research has turned up nothing to suggest she may have done porn), but holy crap, the actress looked like Langer’s Rayanne character in every way except for the multi-colored hair, and had the same voice and mannerisms. Not to mention that the acting in that scene was probably the best I have ever seen in a porn video, suggesting that the couple in the scene were genuine, trained actors.
Has anyone mentioned Jimmy Hoffa yet?
Back in 1999-2001 there was a TV show called It’s Like, You Know…. It was supposed to be the L.A. version of Friends. I haven’t seen it since but I recall really liking it at the time. Apparently it was just me.
She was in that but I didn’t remember until I looked her up on IMDb.
Also in that show was Evan Handler, who plays Charlie Runkle on Californication.
We all know the real Elvis switched places with Sebastian Haff. 
There’s a similar thing going on with Michelle Stacy, the little girl who provided the voice of Penny in the first The Rescuers movie. IMDB notes she had a small part in the Logan’s Run TV show and was in some Peter Pan Peanut Butter commercials way back when, but seems to have disappeared after that.
A lot of people wondered where Roberta Pedon had disappeared to, but once Al Gore invented The Internet, those in the know reported to the world that she had died of liver disease in 1982 at only 28 years old.
Found him.
“Schoeffling lives with his wife, Valerie L. Robinson of Virginia, also a former model, in Newfoundland, Pennsylvania. They have two children, Scarlet and Zane.”
Oh that was from your cite. Not acting anymore is not the same as disappearing. Lots of people have to stop acting.
Vinnie Vincent, who was in KISS for a few years in the 80’s and then had a brief solo career, is currently MIA I believe. He lived for years as a hermit somewhere outside of Nashville, where he passed his time by suing Gene Simmons, beating his wife, scamming his fans, and being a general crazy person. At one point he started the “Official Vinnie Vincent Message Board” and was charging some outrageous membership fee to post on it. The board turned out to be mostly Vinnie posting rants and other gibberish behind various sock puppets. Anyway, I heard that his house in TN was suddenly vacated about a year ago, and no one has seen him. I assume he’s holed up somewhere hiding from creditors/lawsuits.
If only we could convince Nic Cage that it’s okay to quit acting…
I did, in the original post of this thread.
Does anyone know the current whereabouts of Question Mark (of ? And the Mysterians fame…the guys who performed “96 Tears”).
Wiki has him mentioned up through the middle 2000s, then says that the band still plays without him.
