Lady Caroline Lamb's great claim to immortality is that she coined the phrase "mad, bad, and dangerous to know" about Lord Byron. This film is largely about their brief but tempestuous affair, which scandalised Regency high society, although the scandal was mainly that they weren't as discreet about it as they should have been! Sarah Miles is perfectly cast as the highly-strung, irrational aristocrat, a girl far too high-spirited for the polite society she had to live in. It's a difficult, and sometimes humiliating role, but she carries it off with great style. Richard Chamberlain brings almost nothing to the role of Lord Byron, other than pouting a lot and the occasional bit of sneering. He looks suitably dashing though, and I guess they thought that was all that was required at the time, even though Lord Byron himself wasn't reputed to be particularly handsome (Gabriel Byrne did a far more effective job in Ken Russell's "Gothic"). Laurence Olivier, by contrast, makes a dynamic Duke of Wellington, with whom Caro has a one-night stand. The film is very well-made, with immaculate attention to period detail, but it's ultimately a depressing film, as Caro is so clearly going to be doomed by her own irrepressible personality.
