Yes the first things you notice in the older movies now is the smoking and the conversation between men and women and of course the fashions and house interiors. The guy that was constantly trying to get a date with Lauren Hutton was painful................at one point in her modelling career she was the highest paid model in the USA and some of her magazine covers were huge sellers at the time.Funny you mention Adrienne Barbeau, when I first saw her in Someone's Watching Me I was thinking that's the gal from The Fog! Otherwise great info about Carpenter and his various relationships...
One thing I forgot to mention earlier about Someone's Watching Me is I think it's a terrific time warp into the 70s - sexual harassment of women in the workplace was probably fairly common back then, it's as if the men didn't understand that no means no. It's actually pretty perturbing to watch, thank goodness the times and attitudes have changed!
