In being a children’s film, Invisible Mom is somewhat of a change of pace for Fred Olen Ray. Not that much of a change – the effects are still cheap and cheesy; Olen Ray still employs his bimbos – Scream Queen Brinke Stevens appears as a psychiatrist – except they keep their clothes on. Olen Ray also has on board as Executive Producer actor Andrew Stevens who has produced and directed a stack of bad action movies in the 1990s (and under whose Royal Oaks production company banner Invisible Mom is made), while Stevens has also brought along his mom Stella who plays the nosy next-door neighbour.

Fred Olen Ray designed the invisibility matte effects here himself and they are expectedly cheap and unconvincing. He does conduct the effect of an invisible person being reconstituted from the skeleton to the epidermis, prefiguring the more impressive hi-tech variation in Hollow Man (2000), but the effect is so cheaply conducted here that one can clearly see that the skeleton is only an anatomical model. Invisibility films as a rule tend to sink or swim depending on the conviction of their effects and considering the cheapness with which Olen Ray is conducting his effects, that does not leave much else to the film. Indeed, with Olen Ray’s semi-clad bimbos and cheerfully cynical one-liners kept under restraint by the making of a children’s film, there is not much of anything to Invisible Mom at all. Olen Ray also makes the assumption that many children’s film do and pitches the supporting characterizations as shrill one-dimensional caricatures – Russ Tamblyn’s scheming lab supervisor, Stella Steven’s nosy neighbour, the school bully.

Invisible Mom is not a film where the plot falls into the realms of credibility – one of the major plot devices is when villain Russ Tamblyn schemes to have father Barry Livingston incarcerated as insane and his son sent to an orphanage just because Livingston makes the claim he has invented an invisibility formula. In the US, psychiatric incarceration against one’s will is determined on the basis of whether one’s behaviour is a demonstrable danger to one’s self or to others, and certainly no child would ever be placed in an orphanage while the mother is still present, let alone still married to the father.

Fred Olen Ray stacks the film with his usual genre in-references. Being an invisibility film, the family are named Griffin after the lead character in The Invisible Man (1933) and its H.G. Wells source novel. When Barry Livingston places a parcel in the Out tray, the letter beneath it is clearly addressed to ‘Larry Talbot, Llanwelly, Wales’ – the lead character and location for the Lon Chaney Jr The Wolf Man (1941). Peculiarly, the teenage son Trenton Knight has posters for the Z-grade caveman movie Eegah (1962) on his wall and the film is later seen screening on tv.

Fred Olen Ray and principal cast members Dee Wallace, Trenton Knight and Barry Livingston later returned with a sequel Invisible Mom 2 (1999). Around the same time, Olen Ray also made Invisible Dad (1997), which was also a children’s film about invisibility and featured Russ Tamblyn, although is unrelated to this film.
