I saw this film when it first came out, when I was only 14 and VERY impressionable when it came to love, and what it was capable of making you do to get and keep it. Have watched it dozens of times since then (have it on VHS). It's a beautiful, romantic, and very pretty film -- from the gorgeous setting, to the Victorian costumes, to the old-world manners of the day.
One can only wonder "what if", when watching Chris Reeve in films like this when he was at the height of his powerful physicality and gorgeous looks and that killer smile. Similar to watching Patrick Swayze in "Dirty Dancing". To see what they were in their youth and naivete that things would always stay that way for them. But then reality rears its ugly head, and they're gone, just like that. Sad...
I'll check out SIT again, and try to come up with some more BBM parallels to add.
