Relax, I'm not planning on writing any spoilers. I'm not sadistic. :)
All I'm going to say is, Wow. This movie, based on the book Becoming Jane Austen by Jon Spence, is basically about the rumored romance between a 21-year-old Jane Austen (played by Anne Hathaway) and Thomas Lefroy (James McAvoy-- one of the best actors today, in my opinion). As the tagline for the movie goes, "Their love story was her greatest inspiration."
Becoming Jane is undoubtedly the best romantic period film I've ever seen. The cinematography is amazing; the music hauntingly beautiful; and the acting, in British accent now, utterly brilliant.
Of course other Jane Austen movies like Sense and Sensibility and Pride and Prejudice are still on top of my Movies To See list. But I doubt that any of those two will leave me as entranced.
For the fans of Jane Austen, go watch this film. For those who have never read any of her novels, watch it and I'm sure you'll be converted.
Just make sure you resist the urge to go snooping on the Internet for plot summaries or in-depth movie reviews. And if possible, try not to watch the trailer. Some of the good parts are shown there.
