When I was a kid I mistakenly saw a TOO INTENSE movie at The Flick theater in Colorado Springs. Its imagery haunts me to this day, and I seek a revisit to exorcise a few scenes from by brain. Problem: I don’t know the title of the movie. I do remember the setting was an “insane asylum”; there was an intense straight-jacket “fitting” scene; a scalding water bath scene; and a “dungeon” where lost souls could look up through a grate at passersby. Seems it was based on the biography of a famous historical figure. Perhaps a music composer. Help. Thank you.
