Kirk tries really hard, and has some amazing scenes of non-verbal acting greatness, but quite often he's a two-note nutcase, going from really nice to really angry and violent. There's not much more to the film than this. Seeing it again recently makes me wish they had taken a few more risks with non-formulaic elements.

I enjoyed seeing a young John Banner playing a Dutch tourist who helps the police pursue Kirk. He's far more pleasant than the caricature we all remember him as: the bumbling Sgt. Shultz from "Hogan's Heroes"

The kid from "Hans Christian Anderson" is here too, playing Kirk's sidekick instead of Danny Kaye's. And Paul Stewart, the guy who was Kane's valet in "Citizen Kane" is the cop. He was in a TON of television in the 60s.
