When this film was released in 1997 the 'special effects', such as they are, were poor. They would have been dated even for the 1980s, and even some films made in the 1970s and 1960s have had the same or better SFX work. Certainly no-one involved in the production of this film was looking for an Oscar. It's a wild departure from director Fred Olen Ray's usual stuff, most of which has the word "Bikini" in the title (Bikini Pirates, Bikini Chain Gang, Bikini Girls from the Lost Planet, etc) and are little more than T&A flicks, but here we are with a film rated "U" and aimed squarely at the kiddies. You've got to give him credit for diversifying!! This was a minor direct-to-video cult hit which later resulted in a couple of sequels - Invisible Mom 2 and Invisible Dad. Dee Wallace-Stone (whose career went downhill fast after 1982s "E.T.) plays the 'invisible mom' of the films title and would return for the sequel. Russ Tamblyn (whose career had been in free-fall even longer since 1961s "West Side Story") plays the villainous Dr. Woorter. It's probably fair to say that most of the cast were at the point in their careers where they would be prepared to work on almost anything just to pay the bills that month - except maybe young Trenton Knight as Josh. It's rather telling though that although he worked prior to this movie, this child actor didn't work again after the sequel, "Invisible Mom 2". Maybe the film was cursed. After all, he wasn't that bad in this film. For a child actor, he's pretty good - no better or worse than any of his more experienced co-stars.
As mentioned above, the "invisibility" effects are naff to say the least, the direction is poor, the writing obvious and the acting nothing to write home about. There are plenty of worse films out there though, and for anyone under the age of about ten, this film will no doubt be quite watchable. Most adults will probably want to do a disappearing act of their own while it is on though, and I wouldn't blame them one bit!
