A great actor! I remember him in the most excellent movie, Robin Hood, with another great actor Basil Rathbone. I first saw this movie as a very young kid and it remains one of my most favourite movies.
This is a very good documentary, on YouTube, about Errol. I immediately noticed he died very young. Very interesting, very sad.

I also found this movie on YouTube, that he starred in, just a few years before his death.
