I've done similar research before. There was one of the cast members of My Brother and Me. I found him on Facebook and he seems to have fallen into regular living which I think is the case with a lot of these people. The acting gig ended and they faded into everyday life.

Judy from Family Matters never did stay on the show. They never did that much with her anyway. As she got older, she went into the adult entertainment business.

There haven't been too many people I've looked up who didn't have at least some tidbit of info on their current whereabouts and what they were into. It's a popular topic for gossip/entertainment articles, and there are plenty of them.

The little girl off of Aliens, Newt. It was her first and last acting experience.

Claudia Wells... AKA Jennifer in the first Back To The Future film.

Rick Moranis, actor who dropped off of everyone's radar almost 20 years ago, is now looking to get back into acting... just not in a Ghostbusters cameo.

This may be the second best news I've heard all day, topped  only by finally getting my hands on some of onipar's sculpts. I adore Rick Moranis and can't wait to see what role/roles he chooses.

She became a teacher.

I can think of a few people that dropped off the face of the earth that were former members of RetroJunk, Sense of Self, Captain Howdy, Nippy the Fish, Frito 23 and pirate ninja 6!

Woody Woodpecker.

When was the last time you heard him do his trademark laugh?
