The Griffin family is your typical suburban family with your typical suburban family problems. Dad (Barry Livingston) is a slightly eccentric scientist/inventor having problems standing up to his stuffy, impossible-to-impress boss. Son (Trenton Knight) is having a tough time dealing with the neighborhood bully and has just been grounded for not doing his chores. And Mom (Dee Wallace Stone), well, she has even bigger problems when she accidentally ingests an invisibility serum created by her husband and disappears from sight. After overcoming her initial horror, mom ends up using her newfound powers to help out each member of her family while her husband scurries to create an antidote to return her to normal.
No genre is safe from director Ray; he can churn out the sleaziest T&A fest to the mildest and most harmless kiddie-oriented trifle. Despite the hokey blue screen special effects and the silly screenplay, this passable kids film will no doubt please the 10 and under crowd. Most adults may want to pull a disappearing act of their own while it's playing, but some others may enjoy the appearances from such cult celebrities such as Russ Tamblyn, Stella Stevens, John Ashley (in his first role in many years; which turned out to also be his last) and Brinke Stevens. Dee Wallace's ingratiating and enthusiastic lead performance is a major plus and she helps keep it all watchable. Though listed as 1997 on here I am pretty sure it was actually made in 1995. A minor video and cable hit, it was followed by two sequels; INVISIBLE DAD and INVISIBLE MOM II.
