There's something about Dead Ringer which keeps it from being in the same league as other Bette Davis films like Whatever Happened to Baby Jane or All About Eve. Surely it runs at least 20 minutes too long and the central conceit, Davis playing dueling twins, is jettisoned far too quickly to get on with the actual plot. The ending is a bit of an anti-climax, all things considered, but you know what? This is a lavish production with Davis front and center throughout. A whole range of problems comes to mind with taking someone else's identity, though the movie never really pummels the audience with those issues. Maybe it wants the audience to think about them independently. Maybe the movie just doesn't care to think any of those things through or show the problems on screen. Either way, Dead Ringer is still recommended.
