Jenny Agutter made another interesting movie, “Walkabout” (1971).
“An American Werewolf in London” (1981) wasn’t bad, either.
(Dame) Jenny Agutter is still lovely in late middle age. She has guest-starred in many programs over the years and had a great part in a mini-series of Edith Wharton’s “The Buccaneers.”
According to Wikipedia, she 64 and still working steadily. On the “bad SF” front, she was in “Amazon Women on the Moon” in 1987.
I get her mixed up with Cherie Lunghi, also a British actress who has worked steadily for decades. Look them both up and see if they aren’t dead ringers.
