Just watched this on TCM and, fortunately, recorded it so I can go back and rewatch it, but wanted to get other people's input.
Was that Beverly D'Angelo as one of Kelly's bridesmaids? She was on screen for a second or two at most, but it really looked like her.
If you're thinking of the girls in the wedding scene at 1:39:20, the answer is unfortunately no.
To go on a slight tangent for a sec, if D'Angelo was starring as Kelly, I'd probably be more likely to buy the main character's extreme infatuation with Kelly. Cybill is very cute, but kind of shallow.
The girl really is irrelevant. The problem is with Lenny. He's searching for a unicorn; something that doesn't exist. Until he deals with his own issues, no woman will ever be right for him. Sure, at first he'll think they'll absolutely wonderful but that feeling will soon pass.
Woman, man! That's the way it should be Tarzan. [Tarzan and his mate]
