Was Mommie Dearest panned critically? It's considered a camp cult classic now, but I can't recall how it was received back then.
Jake's IMDB listing shows a flurry of work before PM, but only one movie credit afterward.

And that film apparently sat unreleased for four years.
There is mention of the name of a kid he beat in the Episode I auditions, but no idea if it's the kid we see on the DVD extras.

It doesn't make for good gossip, but some child actors do decide to simply "retire" from the business.
