The Mysterious Mr. Valentine

It's an implausible romp and the switches between romantic comedy and serious criminal investigation makes you think that the film can't really settle on its identity.

Despite that, the script, cast and the characters manager to keep your interest for the hour.

It's silly, confusing and ultimately a lightweight B movie.

There's a genuinely funny moment when the heroine is forced to play a secretary and wear ridiculous coke bottle glasses.

For nostalgia freaks (like me) this film has enough going for it too keep me paying attention.

For others it might be a bit of a letdown.
