This source is useful due to the quote:

"The real star of the film, though, is the very beautiful Helena Bonham Carter, seen here recently in the title role of ''Lady Jane.'' As Lucy Honeychurch, Miss Bonham Carter gives a remarkably complex performance of a young woman who is simultaneously reasonable and romantic, generous and selfish, and timid right up to the point where she takes a heedless plunge into the unknown."

It shows that her performance in the film is not straightforward, but instead that she shows a range in her acting abilities, hacing to express various traits at once. This helps with discussing her varying nature of roles and the differences in her acting peformances from different films.
