Richard Chamberlain as Byron.

"Lady Caroline Lamb is a 1972 film based on the life of the notorious Lady Caroline Lamb (1785-1828), lover of Lord Byron and wife of William Lamb, 2nd Viscount Melbourne (later Prime Minister). The film was written and directed by Robert Bolt and starred his wife, Sarah Miles, as Lady Caroline." -Wikipedia

"Despite its intimations of authenticity, "Lady Caroline Lamb" is less fact than fiction, with a plot that reads somewhat more like "Ryan's Daughter" (original screenplay by Robert Bolt) than like the true history of Lady Caroline. This would be perfectly acceptable if it weren't that the story Bolt tells is so much less fascinating than the story he ignores, and if he were able to give his story some form beyond the rhetoric of theatrical phrase-making that reduces the text of the movie to an endless succession of curtain lines.

As Lady Caroline, Sarah Miles (Mrs Robert Bolt) very much looks the part—at least from the one portrait, of Caroline in page's costume, that I have seen. Her pallor is perhaps too waxen, her manner too distracted, but her performance seems to be reaching for a character not realized in the film. Richard Chamberlain is an absurd Byron, but John Finch is a very reticent and feeling William Lamb—forced to do and say many uninteresting things.

Robert Bolt directs (here, for the first time) in the same style in which he writes with the result that every scene, every grouping, every decision behind the camera or at the editing table is immediately effective and ultimately gratuitous. The settings are sumptuous, the costumes lavish, and the productions glossy to a fault. "Lady Caroline Lamb" is to cinema what the coffee-table book is to literature: a heavy but insubstantial irrelevancy." -R. Greenspun
