There is no question that Fred MacMurray is the reason this film works. MacMurray was a likable, charismatic actor who, in this role, reminds you of the perfect father/grandfather figure. He is a family man who aims high in his experiments, which is why he either winds up looking crazy or extremely intelligent. He helps out some of his college students and wins back his wife, who momentarily grows tired of his kooky experiments. This sequel to “The Absent Minded Professor” is wholesome entertainment and the special effects of the flying car were pretty good for its day. It is funny in spots too. For example, in an exaggerated scene, a disgruntled father tells his son, a college student, “Why, if you weren’t deductible, I’d dis-own you!” We approve this film for all ages.
