One of the mourners to Elekra King at Sir Robert’s funeral in The World Is Not Enough?
Still no.
Bond to Madeleine?
Still no.
Bond to Camille apologizing for ruining her attempt to kill Medrano?
No.
Here’s a clue: “I’m very” is clearly heard. But “sorry” isn’t, in fact the speaker mumbles the word so much so that some may quibble and say we can’t be sure what that third word is, other than it begins with a sibilant…
One of the mourners to Lucia Sciarra? I’m grasping at straws at this point.
Still no.
Wow, I’ve really stumped everyone. Over three months now.
Here’s another clue. The speaker starred in That 70’s show… but not the one you’re thinking about. And some may quibble with the dates.
Doesn’t seem to have sparked any brilliance out here in the hinterlands. Perhaps something a little less ELLIPSIStical?
Group scene. American actress.
Stacey Sutton?
Priscilla Barnes as the new Della Leiter, nearly knocking over her own wedding cake?
(Make the clues obvious enough and even I can get it eventually.)
You’re both wrong.
I guess the clues weren’t obvious enough.
I give up
Hah… I thought this game had died… glidrose you really have stumped us good… 
Lois Chiles was in Dallas, which premiered in the '70s, though she was in it in the '80s. But I don’t remember Goodhead saying anything like that.
Did the character have any other lines than the one we’re discussing?__
It’s not Lois Chiles. It’s not Moonraker, either.
The speaker has many more lines in the first 20 minutes.
It doesn’t fit all your clues but Barbara Bach is from NY and does say “I’m very sorry” in TSWLM…
Valerie Mathis?
No to both.
