Hello Alpe, Thanks for the posts.
I half agree with you on Jack and "The Shining." I always look to the director and writers for a film, actors usually being secondary. Usually. Here, yes. Jack is not a fine actor and gets his fuel from the late 60s and being, as you say,over the top. Remember the movie theater scene in "The Departed"? A clown. However, in support of Jack, 1/2 support, I think his comic interludes in "The Shining" show just how nutty he had become - joking while trying to murder the wife and child. I guess the producers allowed Jack to be cast for his marquee status.
Your "Ip Man" comment arsies sometimes in all action films - why don't the dozen bad guys attack the good guy all at once? Well, drama, suspension of disbelief .... Also, there is some element of fact and tactic. The semi and actual IN fighting against a quick opponent may have your punch miss and hit your own man or miss and leave you open. I practice the katana and 2 never attack one. A slash or thrust against a moving, agile opponent may have you striking your own man. Sort of like a cross-fire.
"Sorcerer" is now in my Netflix queue - thanks. Friedkin? "The Exorcist," "The French Connection," I am up for this film - did not know about it. Thanks again!
