when this film be release in 1997 the pecial effect and such a they be and be poor . they would have be date even for the 1980s and and even some film make in the 1970s and 1960s have have the same or good sfx work . certainly no one involve in the production of this film be look for an oscar . it a wild departure from director fred olen ray usual stuff and most of which have the word bikini in the title ( bikini pirate and bikini chain gang and bikini girl from the lose planet and etc ) and be little more than t and a flick and but here we be with a film rat u and aim squarely at the kiddy . you have get to give him credit for diversify . this be a minor direct to video cult hit which later result in a couple of sequel invisible mom 2 and invisible dad . dee wallace stone ( whose career go downhill fast after 1982s e. t. ) play the invisible mom of the film title and would return for the sequel . russ tamblyn ( whose career have be in free fall even longer since 1961s west side story ) play the villainous dr. woorter . it probably fair to say that most of the cast be at the point in their career where they would be prepare to work on almost anything just to pay the bill that month except maybe young trenton knight a josh . it rather tell though that although he work prior to this movie and this child actor do not work again after the sequel and invisible mom 2. maybe the film be curse . after all and he wasn not that bad in this film . for a child actor and he pretty good no good or bad than any of his more experienced co star . a mention above and the invisibility effect be naff to say the least and the direction be poor and the write obvious and the act nothing to write home about . there be plenty of bad film out there though and and for anyone under the age of about ten and this film will no doubt be quite watchable . most adult will probably want to do a disappearing act of their own while it be on though and and i wouldn not blame them one bit .
