Sam Cooper (Steve Gutenberg) is an attaché in the U.S. State Department when, on the day before his wedding, a dying scientist hands him a formula that induces invisibility, and Sam finds himself fleeing with the maid of honor to escape both Russian and U.S. agents. Hotly pursued by everyone, Sam has to use the formula on himself, inviting a series of minor disasters. Critics have been unanimous in agreeing that this secret formula worked on the plot, the continuity, the pacing, and the acting -- making just about everything invisible and doing it in 3-D. The very decision to make a movie about an invisible man in 3-D should have warned of trouble ahead.
