I'm watching The African Queen.
I'm very glad I don't have to pick a favorite movie (for me an impossible choice), but this one would be in contention if you held a gun to my head.
The acting and direction along with amazing cinematography and a good story means it hits all the right notes for me. Over the years, I have watched this film again and again.
I once read the location filming was difficult. I can imagine the heat, humidity, and bugs must've been maddening--and it went on for weeks on end. Perhaps that's what's part of what makes this film magical for me.
If you need a couple of hours' escape from reality, please do watch.
