DeVito and Schwarzenegger as fraternal twin brothers? Hey, why not? This delightful 1988 comedy by Ivan Reitman--about genetically designed twin siblings who discover each other at the age of 35--works out just fine, thanks largely to great chemistry between the two stars. Despite a certain amount of rough action and tension, the film really gets a lift from the palpable innocence Reitman develops, and the female costars (Chloe Webb and Kelly Preston) bring some interesting texture of their own. This is a film that walked the tightrope of a high concept and completely succeeded. To see how easy it is to stumble in a similar situation, check out DeVito and Schwarzenegger in Reitman's Junior. The DVD release has a full-screen presentation, optional French and Spanish soundtracks, optional Spanish subtitles. --Tom Keogh
