Possibly the greatest Humphrey Bogart film known to man. Bogart gives out a legendary performance as the cynical American who trusts no one, yet when his former lover appears out of nowhere (with her husband) he finds himself caught between two worlds: shall he help his former lover who broke his heart all those years ago? Or shall he help her and risk capture? Also, Claude Rains plays a French colonel in French Colonial Africa - who although the Vichy government has just surrendered to Hitler 2 years before - plays a likable and humorous character who ultimately respects Blaine (Bogart).
An unmissable classic film which makes today's films look like complete rubbish.
Recommended for everyone.
