My favorite period in Bronson's career is the "European Period" from "Adieu L'ami" until "Chato's Land" My second favorite period is his "American Glorious Period" from "Chato's land" until "Death Wish II" I also love his "Classics Co-leads period" when he had co-leading roles in "The Magnificent Seven", "The Great Escape" and "The Dirty Dozen".I like the "Cannon Years" but not that much I only like a couple of movies from that period and Bronson doesn't look tough anymore.In 50's he made some interesting performances and by the end of the decade he had his first leading roles.He dis very little stuff in 90's.
I respect his "European period" very much as he made some interesting films but for me, my favorite period had to be his "American Glorious period" as he seemed to be in full confidence and made some good films (DW 2 not being among them, IMHO). The "Classics Co-leads" period was also an excellent time for him as he made the three amazing blockbusters you mention.
Euro period first then the big Hollywood supporting roles, Dirty Dozen, Great Escape etc. Finally the earlier period w nice turns; Travels of Jamie Mcpherson, Machine Gun Kelly, The Big House, many others. Canon Years Not so much although a few were good. I am very Partial to 'Violent City' Great film.
